For God has not given us the spirit of Fear, but of Love and Power and a SOUND mind. 2nd Timothy 1:7. The Sound mind is the important part in this because a sound mind does not fear, it understands its power  and a sound mind questions everything. Learn to question and research and 'study to show yourself approved, a workman who needed not be ashamed rightly dividing the word of truth.  2nd Timothy 2:5
