But without faith it is impossible to please Him… – Hebrews 11:6

Christian men and Christian women, mark well this fact-that the characteristic of the person whom God will bless is that he believes and acts upon his belief. Without faith it is impossible to please God; but the man of faith is God’s man. And why is this? I answer, because faith is the only faculty of our spirit which can grasp God’s ideal. The greatest man, without faith, cannot tread in the divine footsteps. The ideas of God are as high above us as the heavens are above the earth: and therefore it is not by any fancied vastness of our feeble minds that we can ever rise into fellowship with God. Faith in the sight of God’s thought whispers to herself-“I cannot understand this great thing, nor need I wish to do so. What is my understanding? Perhaps I trust to it too much already. I am called to do what God bids me, without knowing why, and I am glad it is so, for now I can worship Him by bowing before His sovereign will.” There is a capacity about faith for grasping divine promises and purposes, a width, a breadth, a height, a depth, which can hold the infinite truth as no other power can do. Love alone can rival it, for it embraces the infinite God Himself. With the far-reaching plans and promises of God faith alone is fit to deal; carnal reason is altogether out of the lists.

Faith, too, has a great power of reception, and therein lies much of her adaptation to the divine purpose. Self-confidence, courage, resolution, cool reasoning, whatever else they are good at, are bad at humbly receiving. Those vessels which are full already are of no use as receivers; but faith presents her emptiness to God, and opens her mouth that God may fill it. Mercy needs not a jewel, but a casket into which to put her gems, and faith is exactly what she wants. ~ C.H. Spurgeon
