The Divine Mission of Jesus Christ: Creator
Jesus Christ “created the heavens and the earth” (3 Nephi 9:15). He did so through the power of the priesthood, under the direction of our Heavenly Father (see Moses 1:33).
“How grateful we should be that a wise Creator fashioned an earth and placed us here,” said President Thomas S. Monson, “… that we might experience a time of testing, an opportunity to prove ourselves in order to qualify for all that God has prepared for us to receive.”
