"Let your hearts rejoice"

1. 2 Ne. 9: 52
   52 Behold, my beloved brethren, remember the words of your God; pray unto him continually by day, and give thanks unto his holy name by night. Let your hearts rejoice.
2. D&C 100: 12
   12 Therefore, continue your journey and let your hearts rejoice; for behold, and lo, I am with you even unto the end.
3. D&C 128: 22
   22 Brethren, shall we not go on in so great a cause? Go forward and not backward. Courage, brethren; and on, on to the victory! Let your hearts rejoice, and be exceedingly glad. Let the earth break forth into singing. Let the dead speak forth anthems of eternal praise to the King Immanuel, who hath ordained, before the world was, that which would enable us to redeem them out of their prison; for the prisoners shall go free.
