Many Christians do not trust God completely to meet their every need. Their belief in God is limited. Some believe God can heal them, but they can't believe that He could prosper them or change their wayward child. If you have constant faith in God and do not doubt at all, you shall have whatever you ask in the will of God. Believing God and God's Word will get you God's promises. No mountain in life can stand in the way of the God-kind of faith. From Jesus' own lips, we receive the most direct and practical instruction concerning our faith. Believing can only work for you when you have faith in what God's word says. When you believe that God exists and that He loves you and wants to meet your needs, your believing becomes action. In other words, you act on what you believe. When you believe that God exists and loves you, but you don't think He will meet your needs-maybe someone else's needs, but not yours-you are in doubt, or unbelief.
