Fear is nothing more than a lack of faith that will lead you down a path of destruction if your focus is not on God. Proverbs 9:10 The fear of the LORD is the beginning of wisdom: and the knowledge of the holy is understanding. Fear here means respect for there is nothing to fear if we are truly with God. We need not fear what this world can do to us for our witness of Christ as Matthew 10:28 says, And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell. So in conclusion the origin of fear begins in ones self. Psalms 91:1 He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.2 I will say of the LORD, He is my refuge and my fortress: my God; in him will I trust.
