25. How Can They Know

O when I think of all the heathen millions, who've never heard the sound of thy sweet name, Who've never known the miracle of Calv'ry who never can thy great salvation claim, Unless we work and pray till day is done, how can they know, how great thou art?  Unless we give until the vict'ry's won, how can they know? How can they know?

2.

But when they hear that Jesus died to save them, and when they know the grace he doth impart, When Jesus shines his love divine within them, he will transform their sinful heathen heart.  Then they shall sing, my Savior, God, to thee, how great thou art, how great thou art.  Then they shall sing, my Savior, God, to thee, how great thou art, how great thou art.
