Every day I am discovering that people are depressed and defeated because of their past failures and mistakes. They allow their past failures to dominate their present thinking. Because of some past failure, they have convinced themselves that they are no good and they are incapable of doing anything worthwhile. Not only do they doubt their abilities to accomplish anything, but they also down their worth as human beings. Anyone who lives in the past, brooding over past mistakes, will have a difficult time living in the present. If you want to be unhappy, then constantly rethink your past failures. If you want to live victoriously, leave your past failures and disappointments in the past where they belong; instead, seek God's face as you live by faith in the present.
