How do we know that eternal life with Christ is true?

The certainty of eternal life with Christ is founded on the promises made in Scripture, particularly in the teachings of Jesus. In John 11:25-26, Jesus declares, 'I am the resurrection and the life. He who believes in Me, though he may die, he shall live.' This assertion solidifies the Christian premise that faith in Christ leads to everlasting life. Moreover, the resurrection of Jesus serves as a historical and theological cornerstone for this truth. His victory over death assures believers that their faith is not in vain and that ultimately, death has been defeated.

Additionally, the letters of the Apostle Paul, particularly in Romans 8:28-30, reinforce the security and certainty of the believer's future with God. Paul writes that 'those He predestined, He also called; those He called, He also justified; those He justified, He also glorified.' Such affirmations provide a robust framework for understanding the continuity from faith in this life to an eternal existence with Christ in the next. Therefore, the authoritative Word of God, alongside the person and work of Christ, establishes an unshakeable hope for believers regarding eternal life.
