How do we know eternal life is found in Jesus?

In John 17:3, Jesus defines eternal life as knowing the only true God and Jesus Christ whom He has sent. This relationship is not just intellectual acknowledgment but a deep, personal communion with the Creator and Redeemer. The importance of this truth is magnified by the context of His High Priestly Prayer, where He pleads with the Father for those He loves, demonstrating His role as the giver of eternal life. The assurance of eternal life is anchored not in human effort or knowledge but in the sovereign grace of God in revealing Himself through Christ.
