David said, "The Lord, who delivered me from the paw of the lion and from the paw of the bear, He will deliver me from the hand of this Philistine [Goliath]." And Saul said to David, "Go, and the Lord be with you!"
- 1 Samuel 17:37
There is always strength in looking to God, but if the mind rests upon the weakness otherwise than to cast it upon God, it becomes unbelief. Difficulties may arise, God may allow many things to come in to prove our weakness; but the simple path of faith is to go on, not looking beforehand at what we have to do, but reckoning upon the help that we shall need and find when the time arrives.
It was no matter to David whether it was the lion, the bear, or this giant of the Philistines. It was all one to him, for in himself he was as weak in the presence of one as in the other; but he went on quietly doing his duty, taking it for granted that God would be with him.
This is faith.
John N. Darby
