If we confess that Jesus is the Son of God, He dwells in us  -  1 John 4:15

Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God.

The blessing of being indwelt by God Himself is the privilege of all who confess that Jesus is the son of God. This confession is not one of mere intellect but a confession that involves the commitment of one’s person to the Lord Jesus Christ. There is not a closer relationship than for a person to abide in God and have God abiding in them.
