‘The Lord is my light and my salvation; whom shall I fear? The Lord is the stronghold of my life; of whom shall I be afraid?’ Psalm 27:1
If we really believe this verse, we should never fear but it’s not as easy as that. We forget, get overtaken by circumstances or just don’t have time to stop worrying. If we learned by heart various verses it might help. But then again we don’t have time to learn. We can be like a drowning man who won’t take of the life-belt.
