What does eternal life mean according to the Bible?

In John 17:3, Jesus articulates that eternal life is defined as knowing God and Jesus Christ. This goes beyond mere existence or a duration of life; it signifies a profound, personal relationship characterized by knowing and being known by God. It emphasizes that eternal life is a gift granted through grace by faith in Christ, made possible by His redemptive work as the High Priest. This relationship transforms the believer’s life today and ensures their place in eternity with God, reflecting the beauty of grace and the assurance of salvation.
