The one who believes in the Son of God has the testimony in himself; the one who does not believe God has made Him a liar, because he has not believed in the testimony that God has given concerning His Son.

And we know that the Son of God has come, and has given us understanding so that we may 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.

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

He who has the Son has the life; he who does not have the Son of God does not have the life.

By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.

If we receive the testimony of men, the testimony of God is greater; for the testimony of God is this, that He has testified concerning His Son.
