Doctrine & Covenants 19:16-19

For behold, I, God, have suffered these things for all, that they might not suffer if they would repent; but if they would not repent they must suffer even as I; which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit---and would that I might not drink the bitter cup, and shrink---Nevertheless, glory be to the Father, and I partook and finished my preparations unto the children of men.”
