In these latter days, the Lord revealed that “when we obtain any blessing from God, it is by obedience to that law upon which it is predicated” (D&C 130:21). The Lord makes generous promises, and He certifies that He will not vary from these promises, for, said He, “I, the Lord, am bound when ye do what I say; but when ye do not what I say, ye have no promise” (D&C 82:10). – Spencer J. Condie, “Claim the Exceeding Great and Precious Promises,” Ensign (CR) November 2007
