No matter how sincere you may be, if you accept false teachings you are in for a deep disappointment. Recently i heard of a preacher who claimed, "Doubt is crucial to faith." No, it isnt. Doubt is the hall,ark of the double-minded man. NEVER DOUBT GOD. Ask in faith means accepting that God will grant your request and thank him for it. James 4 is a good study chapter for this topic. God fervently desires to pray with your spirit He caused to dwell within you. Doubt and Faith are opposites.
