I will add to Dis-Member's comment from Acts 17:27 that "God did this so that they would seek him and perhaps reach out for him and find him, though he is not far from any one of us."
John 4:24 "God is spirit, and his worshipers must worship in the Spirit and in truth." If we worship, we worship in spirit. This has nothing to do with being part of a group or joining a movement.
Strictly Bob...If you have God, then God exists only within. God is not to be found out there somewhere, out there anywhere. God is the spirit within.
