"No one knows what it is like. No one understands."

"There is no physical pain, no spiritual wound, no anguish of soul or heartache, no infirmity or weakness you or I ever confront in mortality that the Savior did not experience first. In a moment of weakness we may cry out, “No one knows what it is like. No one understands.” But the Son of God perfectly knows and understands, for He has felt and borne our individual burdens. And because of His infinite and eternal sacrifice (see Alma 34:14), He has perfect empathy and can extend to us His arm of mercy. He can reach out, touch, succor, heal, and strengthen us to be more than we could ever be and help us to do that which we could never do relying only upon our own power. Indeed, His yoke is easy and His burden is light."
