This is how we are sure that we have come to know Him: by keeping His commands.

The one who says, “I have come to know Him,” yet doesn"t keep His commands, is a liar, and the truth is not in him.

I am writing to you, fathers,
because you have come to know
the One who is from the beginning.
I am writing to you, young men,
because you have had victory over the evil one.

I have written to you, children,
because you have come to know the Father.
I have written to you, fathers,
because you have come to know
the One who is from the beginning.
I have written to you, young men,
because you are strong,
God’s word remains in you,
and you have had victory over the evil one.

Children, it is the last hour. And as you have heard, “Antichrist is coming,” even now many antichrists have come. We know from this that it is the last hour.

I have not written to you because you don’t know the truth, but because you do know it, and because no lie comes from the truth.

This is how we have come to know love: He laid down His life for us. We should also lay down our lives for our brothers.

This is how you know the Spirit of God: Every spirit who confesses that Jesus Christ has come in the flesh is from God.

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

And we know that the Son of God has come and has given us understanding so that we may know the true One. We are in the true One—that is, in His Son Jesus Christ. He is the true God and eternal life.
