1 John 3:23

But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name,

Jesus answered and said to them, “This is the work of God, that you believe in Him whom He has sent.”

“A new commandment I give to you, that you love one another, even as I have loved you, that you also love one another.

“This is My commandment, that you love one another, just as I have loved you.

Beloved, I am not writing a new commandment to you, but an old commandment which you have had from the beginning; the old commandment is the word which you have heard.

Whoever confesses that Jesus is the Son of God, God abides in him, and he in God.

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