Hope in Change

The sixth and final point I wish to make about the process of repentance is that we must be careful, as we seek to become more and more godlike, that we do not become discouraged and lose hope. Becoming Christlike is a lifetime pursuit and very often involves growth and change that is slow, almost imperceptible. . . We must not lose hope. Hope is an anchor to the souls of men. Satan would have us cast away that anchor. In this way he can bring discouragement and surrender. But we must not lose hope. The Lord is pleased with every effort, even the tiny, daily ones in which we strive to be more like Him. Though we may see that we have far to go on the road to perfection, we must not give up hope.

Change of Heart

When we have undergone this mighty change, which is brought about only through faith in Jesus Christ and through the operation of the Spirit upon us, it is as though we have become a new person. Thus, the change is likened to a new birth. Thousands of you have experienced this change. You have forsaken lives of sin, sometimes deep and offensive sin, and through applying the blood of Christ in your lives, have become clean. You have no more disposition to return to your old ways. You are in reality a new person. This is what is meant by a change of heart.

Becoming As a Child

But King Benjamin, who understood as well as any mortal what it meant to be a man of strength and courage, makes it clear that to be like a child is not to be childish. It is to be like the Savior, who prayed to His Father for strength to be able to do His will and then did it. Our natures must be changed to become as a child to gain the strength we must have to be safe in the times of moral peril.

We are safe on the rock which is the Savior when we have yielded in faith in Him, have responded to the Holy Spirit’s direction to keep the commandments long enough and faithfully enough that the power of the Atonement has changed our hearts. When we have, by that experience, become as a child in our capacity to love and obey, we are on the sure foundation.
