Doctrine and Covenants 75: 1-5

1 Verily, verily, I say unto you, I who speak even by the voice of my Spirit, even Alpha and Omega, your Lord and your God—

2 Hearken, O ye who have given your names to go forth to proclaim my gospel, and to prune my vineyard.

3 Behold, I say unto you that it is my will that you should go forth and not tarry, neither be idle but labor with your might—

4 Lifting up your voices as with the sound of a trump, proclaiming the truth according to the revelations and commandments which I have given you.

5 And thus, if ye are faithful ye shall be laden with many sheaves, and crowned with honor, and glory, and immortality, and eternal life.
