Lesson Introduction
One important question believers ask is: If eternal life is God’s gift through Jesus Christ, how should we live after receiving it?
Some people fear that they must continually earn God’s acceptance through good works. Others misunderstand grace and assume that their actions no longer matter because salvation is a gift.
The Bible teaches us to take a different approach. We are saved by God’s grace, not by our works, yet we are called to live in a way that reflects the new life we have received. Obedience does not purchase eternal life, but our faith should influence our choices, relationships, and conduct.
In this lesson, we will examine how assurance and responsibility work together, why obedience matters, how believers grow, and why we should neither live in fear nor use grace as an excuse for careless living.
Opening Prayer
Heavenly Father, thank You for the eternal life You have given through Jesus Christ. Help me understand the relationship between Your grace and my responsibility as a believer. Teach me to obey You from a heart of faith and gratitude, not from the fear that I must earn salvation. Give me wisdom to understand Your Word, humility to receive correction, and strength to grow in love and righteousness. Help me live in a way that honours Jesus Christ and reflects the new life You have given me. In His name, Amen.
1. Salvation Is a Gift, Not a Reward for Good Works
Scripture — Ephesians 2:8–9 (KJV)
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Not of works, lest any man should boast.”
Explanation
Paul makes it clear that salvation is rooted in God’s grace. We do not earn eternal life by accumulating enough good deeds or reaching a particular level of religious performance.
This truth protects us from trying to purchase God’s acceptance through our efforts.
However, understanding that salvation is a gift does not mean that our choices are unimportant. The next verse explains that believers are created in Christ Jesus for good works.
We must keep these truths together: good works are not the price of salvation, but they have an important place in the life of a believer.
Practical Example
A believer helps someone in need. Rather than thinking, “If I do enough good things, God will give me eternal life,” the believer can serve because they are grateful for the grace already received through Christ.
Remember: We do not work to earn eternal life; we live out our faith in response to God’s grace.
2. Grace Calls Us to a New Way of Living
Scripture — Titus 2:11–12 (KJV)
“For the grace of God that bringeth salvation hath appeared to all men,
Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;”
Explanation
God’s grace does more than tell us that salvation is available. Paul says that grace also teaches us how to live.
Grace does not encourage us to remain careless about dishonesty, hatred, exploitation, or other harmful behaviour. It teaches us to turn away from ungodliness and live with self-control, righteousness, and devotion to God.
Our motivation changes when we understand grace. Instead of obeying God merely because we are afraid of losing His acceptance, we learn to obey because we trust Him and want our lives to reflect His truth.
Growth takes time, and believers may need correction along the way. Grace gives us a foundation for that growth.
Practical Example
A believer who previously used harsh words to control others begins learning to speak with patience and honesty. The change is not an attempt to purchase salvation; it is part of learning to live according to God’s truth.
Remember: Grace does not teach us to live carelessly. It teaches us to live in a way that honours God.
3. We Are Created in Christ for Good Works
Scripture — Ephesians 2:10 (KJV)
“For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.”
Explanation
After explaining that salvation is a gift, Paul describes believers as God’s workmanship, created in Christ Jesus for good works.
Notice the order: verses 8–9 explain that salvation is not earned through works, while verse 10 explains that good works belong to the life God has prepared for His people.
Good works may include showing compassion, speaking truthfully, serving others, caring for family, sharing the gospel, and using our abilities responsibly.
These actions do not make us the source of our salvation. They are ways in which our lives can reflect the grace and truth we have received.
Practical Example
A believer notices a neighbour who needs practical assistance. They offer help within their ability, not to prove that they deserve eternal life, but because love and service are consistent with the Christian life.
Remember: Good works are not the foundation of salvation; they are part of the life believers are called to live in Christ.
4. Obedience Is a Response of Love
Scripture — John 14:15 (KJV)
“If ye love me, keep my commandments.”
Explanation
Jesus connects love for Him with keeping His commandments.
Christian obedience is not meant to be an empty performance designed to impress people. It is a response to the Lord we trust and love.
We must understand Jesus’ words within the wider context of His teaching and the new covenant. Obedience does not mean that we earn eternal life by keeping every command perfectly. It means that our relationship with Christ should influence how we live.
When we discover that our behaviour contradicts His teaching, we should be willing to learn, repent, and make changes.
Practical Example
A believer learns that Jesus teaches truthfulness and love for others. When tempted to lie for personal advantage, the believer chooses honesty, even when telling the truth is uncomfortable.
Remember: We obey Jesus because He is our Lord and because we trust Him, not to purchase the eternal life He gives.
5. We Should Not Use Grace as an Excuse for Sin
Scripture — Romans 6:1–2 (KJV)
“What shall we say then? Shall we continue in sin, that grace may abound?
God forbid. How shall we, that are dead to sin, live any longer therein?”
Explanation
Paul addresses a serious misunderstanding of grace: the idea that because God forgives, believers may deliberately continue living in sin without concern.
His answer is strong: “God forbid.”
Paul is not teaching that believers become incapable of sinning. His point is that the grace of God must not be twisted into an excuse for living under sin’s rule.
Believers are called to understand their new relationship with sin through their union with Christ. They can learn to resist harmful behaviour, seek help, and grow in righteousness.
When we fail, we should not hide behind grace to avoid responsibility. We should acknowledge the failure and respond in a way consistent with the gospel.
Practical Example
Someone who has received forgiveness should not use that forgiveness as an excuse to continue cheating others. Instead, they should take responsibility, correct wrongdoing where possible, and pursue honesty.
Remember: Grace gives us hope and freedom; it is never a justification for deliberately harming others or treating sin as unimportant.
6. Christian Growth Is a Process
Scripture — 2 Peter 3:18 (KJV)
“But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To him be glory both now and for ever. Amen.”
Explanation
Peter tells believers to grow in grace and in the knowledge of Jesus Christ.
Growth involves learning, correction, developing wisdom, and becoming more consistent in how we live. A new believer will not necessarily understand every biblical teaching immediately or demonstrate mature character in every situation.
We should not confuse the need for growth with the need to earn salvation. We grow because we belong to Christ, not to persuade Him to give us eternal life.
At the same time, we should not become comfortable with harmful patterns simply because growth takes time. We can take practical steps to learn and change.
Practical Example
A believer who struggles with impatience begins praying for wisdom, studying biblical teaching about patience, and practising a calmer response during disagreements. Progress may take time, but each step can contribute to growth.
Remember: Spiritual growth is an ongoing process. Keep learning, receive correction, and continue growing in Christ.
7. We Are Called to Continue in Faith
Scripture — Colossians 2:6–7 (KJV)
“As ye have therefore received Christ Jesus the Lord, so walk ye in him:
Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving.”
Explanation
Paul encourages believers to continue living in the Christ they received. He uses the picture of being rooted and built up in Him.
The Christian life is not meant to be based on a single moment of enthusiasm while ignoring the truth afterward. Believers are encouraged to become established in the faith, grow in understanding, and abound in thanksgiving.
Continuing in faith includes learning Scripture, participating in healthy Christian fellowship, praying, serving, and responding to life’s challenges with trust in Christ.
These practices do not buy eternal life. They help believers grow in their understanding of the One in whom their life is found.
Practical Example
A new believer establishes a regular time to read the Bible, joins a healthy Christian community, and asks questions when they do not understand. Over time, these habits help them become more grounded in their faith.
Remember: Continue walking in Christ, becoming rooted in the truth and growing in thanksgiving.
8. Good Works Should Flow from Faith Working Through Love
Scripture — Galatians 5:6 (KJV)
“For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.”
Explanation
Paul explains that outward religious distinctions are not what matter most in Christ. He points instead to faith working through love.
Faith is not merely an argument we win or a statement we repeat. Trust in Christ should shape how we treat people.
Love may be expressed through kindness, patience, generosity, honesty, forgiveness, and concern for those who are vulnerable. It also includes speaking truthfully and setting appropriate boundaries when necessary.
We must not judge the entire reality of someone’s faith by one isolated action. Nevertheless, Scripture calls believers to let their faith influence their conduct.
Practical Example
A believer encounters a person who disagrees with their Christian beliefs. Instead of responding with insults, they speak respectfully, explain their convictions honestly, and treat the other person with dignity.
Remember: Faith is meant to work through love, shaping our relationships and everyday decisions.
9. We Should Examine Our Lives Without Living in Constant Fear
Scripture — 2 Corinthians 13:5 (KJV)
“Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?”
Explanation
Paul wrote these words to the Corinthian church in a particular situation involving questions about his ministry and their response to Christ. The passage calls the Corinthians to examine themselves rather than treating the warning as an invitation to endless anxious self-testing.
Self-examination can be helpful. We can ask whether our beliefs align with the gospel, whether we are treating others honestly, and whether we are willing to receive correction from Scripture.
However, examination should not become a cycle in which we repeatedly inspect every feeling and mistake, hoping to achieve absolute certainty through our own performance.
The wider teaching of Scripture directs us to Christ while also calling us to honest faith and responsible living.
Practical Example
A believer recognizes a pattern of dishonesty. Rather than ignoring it or repeatedly asking whether every mistake means they are unsaved, they acknowledge the problem, seek biblical guidance, and take steps toward honesty.
Remember: Examine your life honestly, but let that examination lead to truth, growth, and renewed trust in Christ rather than endless fear.
10. Let Your Life Reflect Gratitude for the Eternal Life You Have Received
Scripture — Colossians 3:17 (KJV)
“And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.”
Explanation
Paul encourages believers to let their words and actions reflect their relationship with Jesus Christ and to give thanks to God through Him.
Gratitude is an appropriate response to the gift of eternal life. When we understand that salvation comes through God’s grace, we can serve with thankful hearts rather than treating every action as a payment toward our acceptance.
This gratitude should influence everyday life: our conversations, family relationships, work, use of money, treatment of others, and service in the church.
We will not always act perfectly. When we fail, we can acknowledge our responsibility and continue learning to live in a way that honours Christ.
Practical Example
A believer approaches their work honestly, treats colleagues respectfully, and fulfils their responsibilities faithfully. They do these things as part of a life that seeks to honour Christ, not as a way to buy eternal life.
Remember: Let gratitude for God’s gift shape your daily life, and seek to honour Jesus in your words and actions.
