King Benjamin taught that the Savior would “suffer temptations, and pain of body, hunger, thirst, and fatigue, even more than man can suffer” (Mosiah 3:7). Paul wrote that the Savior was “in all points tempted like as we are, yet without sin (Hebrews 4:15; cf. 1 Peter 2:22; D&C 20:22).
Joseph Smith declared to the School of the Prophets that Jesus Christ ”is called the Son because of the flesh, and descended in suffering below that which man can suffer; or, in other words, suffered greater sufferings, and was exposed to more powerful contradictions than any man can be.
But, notwithstanding all this, he kept the law of God, and remained without sin, showing thereby that it is in the power of man to keep the law and remain also without sin; and also, that by him a righteous judgment might come upon all flesh, and that all who walk not in the law of God may justly be condemned by the law, and have no excuse for their sins.“ (Lectures on Faith 5:2.)”
