How do we know that God's gift of eternal life is real?

The assurance of God's gift of eternal life is rooted in the redemptive work of Jesus Christ. Romans 6:9 affirms that Christ, having been raised from the dead, dies no more; death no longer has dominion over Him. His single, once-for-all sacrifice takes the place of the repetitive sacrifices of the Old Testament, serving as the definitive proof of God’s grace. Hebrews chapters 7 to 9 continually reinforce this truth by highlighting that Christ offered Himself once to bear the sins of many, emphasizing the finality and completeness of His redemptive act. This singular offering provides unshakeable assurance of eternal life for all who believe.
