Come, Thou long-expected Jesus, Born to set Thy people free; From our fears and sins release us, Let us find our rest in Thee. Israel’s Strength and Consolation, Hope of all the earth Thou art; Dear Desire of every nation, Joy of every longing heart.
Born Thy people to deliver, Born a child and yet a King, Born to reign in us forever, Now Thy gracious kingdom bring. By Thine own eternal Spirit Rule in all our hearts alone; By Thine all-sufficient merit, Raise us to Thy glorious throne.
