Charles H. Spurgeon, All of Grace:
Trust is the lifeblood of faith; there is no saving faith without it. The Puritans were accustomed to explain faith by the word “recumbency.” It meant leaning upon a thing. Lean with all your weight upon Christ. It would be a better illustration still if I said, fall at full length, and lie on the Rock of Ages. Cast yourself upon Jesus; rest in Him; commit yourself to Him. That done, you have exercised saving faith.…
Let me try again. Faith is believing that Christ is what He is said to be, and that He will do what He has promised to do, and then to expect this of Him.
Words of Grace
