When you’re in the habit of depending on your own strength, you collect a whole entourage of fears (the front-and-center kind, plus all the stealth ones that fly below the radar). Once you stop, they won’t stick around long.
“Let me distrust myself and put my trust in You.” St. Augustine
“I will trust and not be afraid, for the Lord is my strength and my song. . . .” Isaiah 12:2
