Reality is not what happens to you. It’s what you think happens to you. If you change the way you think, it can make a profound difference in your outlook on life.
For example, when I was deep in depression I thought God had abandoned me, and the more I thought that way, the worse my depression became. Through cognitive behavioral therapy and inner healing, I came to see that God had not only not abandoned me but had in fact intervened in my life in an extraordinary and dramatic way in the summer of 1975 to bring me out of a dark crisis into the light of His salvation.
If He chose to intervene in my life then, surely He would intervene in my life again. When the thought that He would never leave me nor forsake me flooded my thinking, I was on the path to the healing of my depression.
