“Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God.”
King James Version (KJV)
4:15 Whosoever shall, from a principle of loving faith, openly confess in the face of all opposition and danger, that Jesus is the Son of God, God abideth in him.
1Joh 4:15 Whosoever shall confess that Jesus is the Son of God. Confession of Jesus Christ in word and life is declared proof of the indwelling Spirit in 1Jo 4:2. God dwelleth in him, and he in God. Here it is proof of God dwelling in us, which means the same thing.
