"Yes, I see you this morning, you that are poor. I am to compel you to come in. You are poor in circumstances, but this is no barrier to the kingdom of heaven, for God hath not exempted from his grace the man that shivers in rags, and who is destitute of bread. In fact, if there be any distinction made, the distinction is on your side, and for your benefit—'Unto you is the word of salvation sent'; 'For the poor have the gospel preached unto them.' But especially I must speak to you who are poor, spiritually. You have no faith, you have no virtue, you have no good work, you have no grace, and what is poverty worse still, you have no hope. Ah, my Master has sent you a gracious invitation. Come and welcome to the marriage feast of his love. 'Whosoever will, let him come and take of the waters of life freely.'"- from Spurgeon's sermon Compel Them to Come It
