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.
