And by this we know that we have come to know him, if we keep his commandments.

The one who says "I have come to know him," and does not keep his commandments is a liar, and the truth is not in this person.

We have come to know love by this: that {he} laid down his life on behalf of us, and we ought to lay down our lives on behalf of the brothers.

By this you know the Spirit of God: every spirit that confesses Jesus Christ has come in the flesh is from God,

And we have come to know and have believed the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him.

This is the one who came by water and blood--Jesus Christ, not with the water only, but with the water and with the blood. And the Spirit is the one who testifies, because the Spirit is the truth.

And we know that the Son of God has come and has given us understanding, in order that we may know the one who is true, and we are in the one who is true, in his Son Jesus Christ. This one is the true God and eternal life.
