Weak Christians

Weak Christians have eyes to behold their discouragements—but none to see their encouragements; they look more upon their corruption than upon their sanctification; upon their disobedience than their obedience; upon their distrust than upon their faith; upon the old man than upon the new—and this keeps them low and weak in spirituals, it causes a leanness in their souls.
