D&C 1: 24 Behold, I am God and have spoken it; these commandments are of me, and were given unto my servants in their weakness, after the manner of their language, that they might come to understanding. 25 And inasmuch as they erred it might be made known; 26 And inasmuch as they sought wisdom they might be instructed; 27 And inasmuch as they sinned they might be chastened, that they might repent; 28 And inasmuch as they were humble they might be made strong, and blessed from on high, and receive knowledge from time to time. . . 38 What I the Lord have spoken, I have spoken, and I excuse not myself; and though the heavens and the earth pass away, my word shall not pass away, but shall all be fulfilled, whether by mine own voice or by the voice of my servants, it is the same. 39 For behold, and lo, the Lord is God, and the Spirit beareth record, and the record is true, and the truth abideth forever and ever. Amen.
