Waiting on the Lord, for the promise given; Waiting on the Lord, to send from Heaven; Waiting on the Lord, by our faith receiving; Waiting in the upper room.
Refrain: The power! the power! Gives vict’ry over sin, and purity within; The power! the power! The pow’r they had at Pentecost.
Waiting on the Lord, giving all to Jesus; Waiting on the Lord, till from sin He frees us; Waiting on the Lord for the heav’nly breezes; Waiting in the upper room.
Waiting on the Lord, longing to mount higher; Waiting on the Lord, having great desire; Waiting on the Lord, for the heav’nly fire; Waiting in the upper room.
