"For after much tribulation come the blessings. Wherefore the day cometh that ye shall be crowned with much glory; the hour is not yet, but is nigh at hand" (D&C 58:4).President Brigham Young said: "Every trial and experience you have passed through is necessary for your salvation" (Discourses of Brigham Young, sel. John A. Widtsoe (1954), 345).

As I put my trust in Him peace comes into my life and I am able to bear my burdens with thanksgiving.
