(and the life was revealed, and we have seen, and testify, and declare to you the life, the eternal life, which was with the Father, and was revealed to us);

This is the promise which he promised us, the eternal life.

Whoever hates his brother is a murderer, and you know that no murderer has eternal life remaining in him.

The testimony is this, that God gave to us eternal life, and this life is in his Son.

These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.

We know that the Son of God has come, and has given us an understanding, that we know him who is true, and we are in him who is true, in his Son Jesus Christ. This is the true God, and eternal life.
