The Father has a body of flesh and bones as tangible as man’s; the Son also; but the Holy Ghost has not a body of flesh and bones, but is a personage of Spirit. Were it not so, the Holy Ghost could not dwell in us.
Doctrine and Covenants 130:22
God is a Spirit: and they that worship him must worship him in spirit and in truth.
And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.
1 John 4:16
