I cannot tell you how many times I've seen people's entire lives disrupted and ministries of God completely destroyed when people are moved by fear to do things they would never do without it. We humans are suckers for this spirit of fear. It paralyzes us and takes us over like a tsunami takes over a coastline village. The heart rate can go from 60-150 in a matter of seconds and this new and elevated stress causes the brain to make irrational decisions that can be as devastating as a category 5 hurricane.
2 Timothy 1:7 says that “God has not given us a spirit of fear, but of power and of love and of a sound mind.”
