Quotes from the same author

The Lord will never forsake or abandon anyone, You may abandon him, but he will not abandon you. You never need to feel that you are alone.
 Joseph B. Wirthlin
How can we love days that are filled with sorrow? We can't-at least not in the moment. I don't think my mother was suggesting that we suppress discouragement or deny the reality of pain. I don't think she was suggesting that we smother unpleasant truths beneath a cloak of pretended happiness. But I do believe that the way we react to adversity can be a major factor in how happy and successful we can be in life.
 Joseph B. Wirthlin

No matter our age, our circumstances, or abilities... Each one of us can create something remarkable with our lives.
 Joseph B. Wirthlin
As you overcome adversity in your life, you will become stronger. Then you will be better able to help others -those who are working, in their turn, to find a safe harbor from the storms that rage about them.
