1 John 2:23

so that all will honor the Son even as they honor the Father. He who does not honor the Son does not honor the Father who sent Him.

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

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

Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the One who gives new birth loves also the one who has been born of Him.

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.

Anyone who goes too far and does not abide in the teaching of Christ, does not have God. The one who abides in the teaching, he has both the Father and the Son.
