"Now all that God asks of you—and this he gives you—is that you will simply look at his bleeding dying son, and trust your souls in the hands of him whose name alone can save from death and hell. Is it not a marvelous thing, that the proclamation of this gospel does not receive the unanimous consent of men? One would think that as soon as ever this was preached, 'That whosoever believeth shall have eternal life,' every one of you, 'casting away every man his sins and his iniquities,' would lay hold on Jesus Christ, and look alone to his cross. But alas! such is the desperate evil of our nature, such the pernicious depravity of our character, that this message is despised, the invitation to the gospel feast is rejected, and there are many of you who are this day enemies of God by wicked works, enemies to the God who preaches Christ to you to-day, enemies to him who sent his Son to give his life a ransom for many."- from Spurgeon's sermon Compel Them to Come It
