Early in this dispensation, the Lord declared: “… I, the Lord … make every man accountable, as a steward over earthly blessings, which I have made and prepared for my creatures. … The earth is full, and there is enough and to spare; yea, I prepared all things, and have given unto the children of men to be agents unto themselves.” (D&C 104:13, 17)
I understand from this that not only does the Lord have the right to direct me in the use of my earthly blessings, but by making me a steward, he also expects me to find ways to use my blessings – my time, my talents, my possessions – in his service even when he doesn’t give specific directions. He has made me – has made us all – “agents unto [our]selves,” with the responsibility of finding ways to serve him.
