1 John 4:15

15 Whoever confesses[a] that Jesus is the Son of God-God remains in him and he in God.

1 John 4:15 In-Context

13 This is how we know that we remain in Him and He in us: He has given to us from His Spirit.
14 And we have seen and we testify that the Father has sent the Son as Savior of the world.
15 Whoever confesses that Jesus is the Son of God-God remains in him and he in God.
16 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.
17 In this, love is perfected with us so that we may have confidence in the day of judgment; for we are as He is in this world.
