James 1:6 But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind.
When you doubt, are you doubting what God can do, or doubting what you can do for God?
We are human and we do doubt ourselves; this is what prevents us from succeeding when we need to. But this is very different from doubting God!
We should never doubt God and what He is asking of us. Nothing is impossible with God and nothing too difficult for Him.
We are the weak link in the chain – trust God to give you strength to hold that chain together!
