How can I gain eternal life?
What must I do to inherit eternal life?

Definition of Eternal Life

Eternal life is frequently described in Scripture as living forever in a restored relationship with the Creator. The Berean Standard Bible signifies this in John 17:3: “Now this is eternal life: that they may know You, the only true God, and Jesus Christ, whom You have sent.” In this sense, eternal life encompasses more than simply endless existence; it includes fellowship with God, freedom from condemnation, and acceptance as children of God (Romans 8:1–2).


Scriptural Foundations

Throughout Scripture, the question “What must I do to inherit eternal life?” appears directly, such as in Mark 10:17: “As Jesus started on His way, a man ran up and knelt before Him. ‘Good Teacher,’ he asked, ‘what must I do to inherit eternal life?’” This question is at the heart of the human condition.

1. Recognition of Sin

Scripture emphasizes the universal problem: “All have sinned and fall short of the glory of God” (Romans 3:23). Sin separates humanity from God (Isaiah 59:2), creating an impassable breach without divine intervention.

2. God’s Provision in Christ

Jesus atones for sin, fulfilling the promises and prophecies of the Old Testament (Isaiah 53; Luke 24:27). As 1 Peter 2:24 states, “He Himself bore our sins in His body on the tree.” His resurrection demonstrates victory over death and secures believers’ confidence that eternal life is truly attainable (1 Corinthians 15:3–6).

3. Human Response

The required response is to repent (turn from sin) and to believe (trust in Christ). This is summarized in Mark 1:15: “The time is fulfilled…repent and believe in the gospel!” Belief in Christ includes acknowledging His Lordship (Romans 10:9–10).


Faith, Repentance, and Transformation

The person asking how to inherit eternal life faces the demand not just of intellectual assent, but also of a changed heart. James 2:20 notes that “faith without deeds is useless.” While good works do not earn salvation (Ephesians 2:8–9), they flow from genuine faith.

1. Faith Explained

Faith involves trusting in God’s promises, especially concerning the life, death, and resurrection of Jesus (John 20:31). Scholars studying early manuscript evidence (like P52, one of the earliest fragments of John’s Gospel) affirm that this core teaching on faith in Jesus has been transmitted accurately.

2. Repentance Detailed

Repentance, conveyed by the Greek term “metanoia,” means a fundamental change of mind and heart. It starts with sorrow over sin (2 Corinthians 7:10), but leads to a renewed purpose and direction toward God.

3. Transformation Through the Holy Spirit

Genuine faith and repentance invite the Holy Spirit’s work of transformation within the believer (Titus 3:5). Archaeological and textual studies confirm New Testament documents consistently teach that believers receive the Holy Spirit as a pledge of their inheritance (Ephesians 1:13–14).


The Role of the Resurrection

Foundational to inheriting eternal life is the bodily resurrection of Jesus. The apostolic testimony (1 Corinthians 15:1–8) points to numerous eyewitnesses. Many historians—including those outside the community of faith—acknowledge the early belief in the resurrection as pivotal in birthing the Christian movement. Scholarly investigation has long noted that:

• Multiple independent sources attest to the resurrection narratives (e.g., the Gospels, 1 Corinthians 15).

• Early creedal statements found in manuscripts, like the one embedded in 1 Corinthians 15:3–5, date very close to the events themselves.

• The rapid growth of Christianity in a hostile environment suggests genuine conviction based on a transformative event.

Therefore, trusting in the risen Messiah is central to inheriting eternal life, fulfilling passages like Romans 4:25: “He was delivered over to death for our trespasses and was raised to life for our justification.”


Simplicity of the Gospel

Although Christian theology can be profoundly deep, the method of receiving eternal life is straightforward:

1. Acknowledge Sin

Recognizing moral failings and humbly admitting the inability to please God by works (Romans 3:19–20).

2. Believe in Christ Alone

Trusting that Jesus is fully God and fully man (John 1:1, 14), that He died for sins and rose again (1 Corinthians 15:17–20).

3. Call on Him for Salvation

According to Romans 10:13, “Everyone who calls on the name of the Lord will be saved.” This involves personal, earnest surrender.


Consistency of Scripture and Its Manuscript Reliability

From the Dead Sea Scrolls to Codex Sinaiticus and Codex Vaticanus, the remarkable manuscript evidence demonstrates that the biblical record has been preserved with an extraordinary level of fidelity over centuries. Scholarly consensus acknowledges the New Testament as one of the best-attested collections of ancient manuscripts available.

Internal Consistency

Expert textual critics note how variations do not alter the fundamental message of salvation. Passages like John 3:16 remain intact through myriad manuscript comparisons.

Archaeological Corroborations

Site discoveries (e.g., Jericho, the pool of Bethesda in John 5:2) offer tangible support for biblical accounts. These confirmations underscore the historical reliability of Scripture’s framework.


Obedience and Sanctification

Once a person experiences the new birth, obedience to God’s Word and a growing likeness to Christ follow. John 14:15 states, “If you love Me, you will keep My commandments.” Such obedience is not a condition to earn salvation but the fruit of a transformed life in genuine relationship with God.

1. Living by the Spirit

Believers are urged to “walk by the Spirit” (Galatians 5:16). This daily dependence results in love, joy, peace, and other virtues that mark a life dedicated to God’s glory.

2. Growing in Grace

Sanctification—the process of becoming more Christ-like—unfolds over time. The indwelling Holy Spirit empowers consistent growth, accompanied by the encouragement of Scripture.


Glorifying God with One’s Life

The overarching purpose is not just to gain eternal life but to glorify the One who provides it. Matthew 5:16 says, “Let your light shine before men, that they may see your good deeds and glorify your Father in heaven.” This doxological view sees every aspect of life as an opportunity to reflect the character and grace of God.


Answer to the Central Question

To inherit eternal life, Scripture teaches:

1. Repent of sin and its destructive power.

2. Believe in Jesus as the Son of God who died and rose again.

3. Confess Him as Lord, calling on His name for salvation.

4. Walk in the Spirit, growing in holiness and reflecting God’s glory.

Romans 10:9–10 synthesizes this: “If you confess with your mouth, ‘Jesus is Lord,’ and believe in your heart that God raised Him from the dead, you will be saved.”


Final Invitation

The beauty of this question lies in the simple but profound answer found across the pages of Scripture: “Respond to God’s gracious invitation through faith in His Son.” By doing so, you are adopted into His eternal family. May these truths, supported by centuries of manuscript evidence, historical data, and the testimony of countless transformed lives, encourage you to trust wholeheartedly in the risen Christ and share in the promises of eternal life.
