What does eternal life mean according to Jesus?

In John 17:3, Jesus defines eternal life not merely as endless existence but as a profound relational knowledge of God and His Son, Jesus Christ. This means that eternal life begins not just at death but at the moment of faith in Christ, as believers enter into a transformative relationship with God. It emphasizes that to know God is both a spiritual and relational experience, marked by intimacy and personal connection. This is significant because it transcends mere intellectual acknowledgment of God and invites believers into ongoing fellowship and communion with Him.
