When you are filled with self-doubt, and in the grip of your inferiority complex, don’t give up saying, “I can’t do it, I haven’t it in me.” You do have a very big “it” within you. You have the Kingdom of God within you.
God has placed in your personality all the ability you need. You have only to believe in yourself, and strength within you will be released.
In saying the text, try it this way, “God’s abundance, peace, and power are within me. I lack for nothing.”
