You remove fear with faith. Faith allows you to keep hope alive. Hope keeps you alive. The more alive you feel, the less fear can creep in.
My husband is afraid to really live. He exist and can't understand he is in control of whether he lives a rich life or not.
He is so bitter towards me and it is such a shame. It is only that way because I put a stop to his reign of terror. I won't let him get away with what he's being getting by with. He is scared and childish, a paralyzing combination.
You remove fear by learning to lean on God and not your own understanding. Plain and simple.
