Quick answer

Eternal life is defined as knowing the only true God and Jesus Christ whom he sent. Salvation is a living relationship, not merely endless existence.

Overview

Jesus describes eternal life relationally: to know God personally and savingly, and to know him through the Son he sent. This knowledge is more than intellectual; it is the intimate fellowship that the gospel restores. By naming both the Father as 'the only true God' and himself as the one sent, Jesus affirms his unique role as the way to the Father and grounds eternal life in the triune God.

Christ at the center

John declares him plainly: the eternal Word made flesh, the Lamb of God, the great 'I AM' — bread, light, door, shepherd, way, truth, life, resurrection — that you may believe and have life in his name.
