But for the most part Christ finds His people in His own house; but He finds them often in the worst of tempers, in the most hardened conditions; and He softens their hearts, awakens their consciences, subdues their pride, and takes them to himself; but never would they come to Him unless He came to them. Sheep go astray, but they do not come back again of themselves. Ask the shepherd whether his sheep come back, and he will tell you, “No, sir; they will wander, but they never return.” When you find a sheep that ever came back of himself, then you may hope to find a sinner that will come to Christ of himself. No; it must be sovereign grace that must seek the sinner and bring him home.
C.H. Spurgeon
