But without faith it is impossible to please Him: for he that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him. – Hebrews 11:6

Faith always uses the strength that God gives her. Faith has already spent all her own strength, and she so yearns to achieve her purposes that she uses all the power that God will lend her. Faith eats her manna and leaves not a morsel for worms to breed in. Faith, too, can wait the Lord’s time and place. When faith is weak men are in a dreadful hurry, but strong faith does not judge the Lord to be slack concerning His promise. As God achieves His purpose with infinite leisure, He loves a faith that is patient and looks not for its reward this day or the next. “He that believeth shall not make haste”: that is to say, he shall not be ashamed or confounded by present trials so as to rush upon unbelieving actions. Faith leaves times and seasons with God to whom they belong.

God loveth faith and blesseth it too, because it giveth Him all the glory. The true believer will not allow a trace of self-glory to linger on his hands. “Where is boasting then?” was a question once asked in the house of faith, and the searchers examined every nook and corner in every chamber to find it, but they found it not. Then they said to faith, “Where is boasting?” She answered, “I shut him out.” “It is excluded,” shut out, and the door fastened in its face. You do not believe God if you boast of what you are doing: least of all do you believe if you pride yourself in your faith, for faith is not mistrustful of her God but of herself. Faith looks to God to keep her alive as well as to fulfil the promise that He has made to her. ~ C.H. Spurgeon
