Central Truth
God’s covenant reshapes identity and calls His people to wholehearted obedience.
Learning Objective
By the end of this lesson, you should be able to explain how God’s covenant changed Abram’s identity, why covenant blessing carries responsibility, and how believers should allow their relationship with God to influence their conduct, commitments and leadership.
Key Bible Verse
“And when Abram was ninety years old and nine, the LORD appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect.”
Genesis 17:1, KJV
Sound Biblical Teaching
Genesis 17 opens when Abram was ninety-nine years old. He had been eighty-six when Ishmael was born. Approximately thirteen years had passed since the events recorded in Genesis 16.
God appeared to Abram and introduced Himself:
“I am the Almighty God; walk before me, and be thou perfect.”
Genesis 17:1, KJV
The expression translated as Almighty God presents God as sufficient, powerful and fully capable of accomplishing His purpose. Abram’s circumstances had changed with age, but God’s power had not weakened.
God commanded Abram to walk before Him and be perfect. In this context, perfection does not mean that Abram would never make another mistake. It communicates wholeheartedness, integrity, maturity and undivided commitment.
God was calling Abram to live consciously before Him. Abram’s life was not to be directed only by what other people could see. He was to live with an awareness that God saw his motives, decisions and conduct.
God then reaffirmed His covenant:
“And I will make my covenant between me and thee, and will multiply thee exceedingly.”
Genesis 17:2, KJV
Abram fell on his face as God spoke. His posture expressed humility, reverence and surrender.
God declared that Abram would become the father of many nations. He then changed his name:
“Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many nations have I made thee.”
Genesis 17:5, KJV
The name Abram is commonly understood as “exalted father.” The name Abraham expressed his covenant identity as the father of many nations.
At that moment, Abraham had only one son, Ishmael. Sarah had not yet given birth to Isaac. However, God changed Abraham’s name before the full promise became visible.
Every time Abraham introduced himself, heard his name or responded to it, he was reminded of what God had declared concerning his future.
God promised that nations and kings would come through Abraham. He also established His covenant with Abraham’s descendants and promised to give them the land of Canaan.
“And I will be their God.”
Genesis 17:8, KJV
The greatest part of the covenant was not merely land, descendants or national influence. It was the relationship expressed in God’s declaration that He would be their God.
God then gave Abraham the sign of circumcision. Every male within Abraham’s household was to be circumcised. This included those born within the household and those acquired from outside it.
Circumcision would serve as an outward sign of the covenant between God and Abraham’s family.
God also changed Sarai’s name:
“As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be.”
Genesis 17:15, KJV
God promised that Sarah would bear a son and become the mother of nations. Kings would come through her.
Abraham fell upon his face and laughed. He considered his age and Sarah’s age and struggled to understand how they could have a child.
Abraham then said:
“O that Ishmael might live before thee!”
Genesis 17:18, KJV
Abraham cared for Ishmael and wanted God’s blessing to continue through him. God responded by confirming that Ishmael would be blessed, fruitful and the father of twelve princes.
However, God made a clear distinction:
“But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.”
Genesis 17:21, KJV
Ishmael would receive blessing, but Isaac would carry the specific covenant promise.
After God finished speaking, Abraham obeyed immediately. On that same day, he circumcised Ishmael and every male in his household.
Abraham did not delay obedience until the promise was fulfilled. He acted while Sarah was still without the promised child.
Clear Explanation
God revealed His sufficiency before giving His command
God said, “I am the Almighty God,” before saying, “walk before me.”
The command was grounded in God’s identity and power.
Abraham was not expected to live faithfully through personal strength alone. He was called to depend on the Almighty God.
Your obedience should also begin with an understanding of who God is.
God is not asking you to trust an uncertain character. He is faithful, wise, powerful and fully aware of your circumstances.
When responsibility feels greater than your ability, return to the sufficiency of God.
Walking before God requires personal integrity
God commanded Abraham to walk before Him.
Walking before God means living with a continuous awareness of His presence and authority. It requires consistency between your public conduct and private choices.
A person may impress people while neglecting integrity. They may appear spiritual in public but become careless when nobody is watching.
Ask yourself:
- Would I make this decision if everyone knew?
- Would I act this way if I remained conscious of God’s presence?
- Does my private conduct agree with my public confession?
- Am I trying to protect an image rather than build character?
Faith that obeys does not perform only for an audience. It honours God in private and public.
Biblical perfection means wholehearted commitment
The command to “be thou perfect” should not be understood as a demand for immediate sinless perfection.
Abraham had already made mistakes, and later passages would reveal further weaknesses. God was calling him towards maturity, integrity and complete commitment.
A wholehearted person can still need correction. The difference is that they do not deliberately divide their loyalty between God and persistent disobedience.
Spiritual maturity does not mean that you never fail. It means that you continue submitting every area of your life to God.
Covenant identity came before visible fulfilment
God called Abram Abraham before Isaac was born.
His new name described a future that was not yet visible.
God’s declaration became the foundation for Abraham’s identity. His circumstances no longer had the final word concerning who he was becoming.
Believers must also learn to receive their identity from God rather than from:
- Past failures
- Family labels
- Social status
- Financial conditions
- Other people’s opinions
- Personal insecurity
- Temporary disappointment
However, biblical identity is not empty positive language. It is grounded in God’s Word and accompanied by responsibility.
A changed identity should produce changed conduct
God did not merely give Abraham a new name. He gave him a command, a covenant sign and a responsibility towards his household.
Identity and obedience belong together.
It is not enough to declare:
- I am blessed.
- I am chosen.
- I am called.
- I am a leader.
- I am a child of God.
Ask:
- How should this identity change my behaviour?
- What responsibility accompanies this privilege?
- What standard must I now uphold?
- How should I treat other people?
- What must I stop doing?
A spiritual title without corresponding character becomes an empty claim.
Sarah was included by name
God corrected Abraham’s attention by declaring that Sarah would bear the covenant son.
The promise was not simply about Abraham becoming a father. Sarah had a defined place within God’s purpose.
She was not a secondary figure whose contribution could be replaced without consequence. God changed her name and declared her future.
God’s plans recognise people whom others may overlook. Do not assume that your role allows you to ignore the value, calling or contribution of those connected to you.
Healthy leadership acknowledges the people whom God has included.
Abraham struggled to believe the method
Abraham had believed God’s general promise, but the announcement concerning Sarah still appeared impossible.
He laughed because the physical circumstances seemed overwhelming. He was nearly one hundred, and Sarah was ninety.
Faith can be genuine while still requiring growth in specific areas.
You may trust God generally but struggle when His direction becomes personal, costly or beyond your preferred method.
Bring that struggle honestly before God. Do not allow questions to become permanent refusal.
Abraham asked God to bless Ishmael
Abraham had affection and concern for Ishmael.
God did not reject Ishmael. He promised to bless him, multiply him and make him fruitful.
However, God did not change the covenant plan to accommodate Abraham’s previous decision.
God’s mercy can operate within a situation without declaring that every earlier decision was correct.
He may care for people affected by your mistake while still directing you back to His original purpose.
Blessing and covenant assignment are not identical
Ishmael received blessing, but Isaac carried the covenant promise.
Not every person has the same assignment. Not every opportunity carries the same purpose.
Comparison becomes dangerous when people assume that another person’s role diminishes their own value.
God’s blessing can be present in different ways. Honour your responsibility without trying to take another person’s assignment.
Covenant carries responsibility
Abraham received promises, but he also received instructions.
The covenant was not merely a guarantee of benefits. It required Abraham to obey and to lead his household in obedience.
Many people desire promise without responsibility. They want divine favour without discipline, identity without integrity and influence without accountability.
God’s blessing should produce greater faithfulness, not greater carelessness.
Abraham obeyed without delay
The chapter repeatedly states that Abraham acted on the same day God spoke.
Circumcision was personal, painful and costly. Abraham still obeyed immediately.
He did not say:
- I need more time to think.
- I will obey after Isaac is born.
- I will begin with a few people.
- I will wait until the instruction becomes easier.
- I will obey only the parts I prefer.
Immediate obedience demonstrated that Abraham took the covenant seriously.
Delayed obedience often reveals resistance. Where God’s instruction is clear, act responsibly and promptly.
Abraham led his household through personal example
Abraham was circumcised alongside Ishmael and the other males in his household.
He did not require others to accept a responsibility that he refused to carry himself.
Leaders must practise what they expect from others.
Parents, pastors, managers, teachers and community leaders lose credibility when they demand discipline, integrity or sacrifice from people while exempting themselves.
Lead from the front. Accept the standard before enforcing it.
Practical Application
1. Examine the identity that directs your life
Complete the statement:
“I often see myself as __________________________.”
Consider whether your answer is based on God’s truth or on past experiences.
You may have accepted identities such as:
- The rejected one
- The person who always fails
- The forgotten child
- The victim
- The unsuccessful one
- The person who started too late
- The person nobody supports
- The person who cannot change
A painful experience may describe something that happened to you, but it does not have to define your entire future.
Ground your identity in Scripture and allow it to shape responsible action.
2. Connect every promise with responsibility
When you claim a biblical promise, ask what response it requires.
For example:
- If God gives wisdom, use it responsibly.
- If God provides resources, practise stewardship.
- If God gives influence, serve people.
- If God forgives you, extend forgiveness.
- If God gives leadership, protect those you lead.
- If God opens an opportunity, work with excellence.
Do not separate receiving from responsibility.
3. Walk before God in private
Identify one area where your private behaviour needs to agree more closely with your public values.
This may involve:
- Financial honesty
- Online activity
- Communication
- Sexual integrity
- Time management
- Anger
- Business practices
- Treatment of family members
- Confidential information
- Personal discipline
Choose one practical correction and begin immediately.
4. Stop using spiritual identity to avoid correction
Statements about identity should not become shields against accountability.
Saying, “God knows my heart,” does not remove the need to change harmful behaviour.
Saying, “I am under grace,” does not justify persistent disobedience.
Saying, “I am called,” does not make every decision correct.
True identity in God creates humility, teachability and responsibility.
5. Recognise the people included in the purpose
Abraham needed to understand Sarah’s defined place in the covenant promise.
Examine your plans and ask:
- Whose contribution have I overlooked?
- Who needs to be consulted?
- Who carries part of this responsibility?
- Am I taking credit for a shared achievement?
- Have I ignored someone because they appear less visible?
Strong leadership gives appropriate recognition and responsibility to others.
6. Distinguish care from control
Abraham cared about Ishmael, but his concern could not replace God’s direction concerning Isaac.
You can love someone without controlling their assignment. You can support them without forcing your expectations upon them.
Parents must not require children to fulfil abandoned personal dreams. Leaders must not treat people as extensions of their own ambition.
Support people as they discover and fulfil their God-given responsibilities.
7. Act on clear instruction
Review any responsibility you have delayed.
Perhaps you need to:
- Correct a mistake
- Apologise
- Complete an application
- Establish a boundary
- Begin a disciplined routine
- End a dishonest practice
- Keep a commitment
- Seek professional assistance
- Start serving
- Organise your household
- Complete an assignment
Do not wait for emotion to agree with obedience.
8. Lead by example
Before asking others to change, examine your own conduct.
If you want honesty, speak truthfully.
If you want punctuality, arrive on time.
If you want prayer in your household, pray consistently.
If you want financial discipline, manage your own spending.
If you want respect, treat people respectfully.
Your example gives weight to your instruction.
9. Establish a covenant reminder
Circumcision functioned as a covenant sign for Abraham and his household.
Under the New Covenant, Christians are not justified or accepted by God through physical circumcision. Salvation is received through faith in Jesus Christ, and Scripture emphasises the transformation of the heart.
You can still establish healthy reminders of your commitment to God, such as:
- A written declaration
- A regular communion practice within appropriate church guidance
- A Bible study routine
- A prayer journal
- A family prayer time
- A record of commitments
- A visible Scripture
- Accountability with a mature believer
The reminder does not replace obedience. It helps you remember the responsibility you have accepted.

Prayer
Heavenly Father, thank You for revealing Yourself as the Almighty God. Teach me to walk before You with integrity, maturity and wholehearted commitment. Help me to receive my identity from Your truth rather than from failure, fear or the opinions of others. Forgive me for seeking blessing without accepting responsibility. Show me every area where my conduct must change. Give me the courage to obey Your clear instructions without unnecessary delay. Help me to recognise the people You have included in Your purpose and to lead others through faithful example. Let my identity, character and actions honour You. In Jesus’ name, Amen.
Action
Examine one area where your declared identity and daily conduct are not fully aligned.
Complete the following statements:
The identity I have accepted from God’s Word is:
The behaviour that should accompany this identity is:
The area where my conduct needs to change is:

I will take this action by:
Choose one biblical statement concerning your identity and write it somewhere visible. Read it every morning for the next seven days. Each time you read it, identify one responsibility connected to that identity and act upon it.
Covenant identity is not merely a new name. It is a call to walk before God with integrity, responsibility and immediate obedience.
