“…cleanse first that which is within the cup and platter, that the outside of them may be clean also.” -Matthew 23:26

O Christian men and women, my brethren and sisters in the faith of Jesus Christ! How many there are of you who are content just to be saved, and merely to enter heaven. How many do we find who are saying “Oh! if I can but just get in at the door-if I can simply be a child of God!” and they carry out their desires literally, for they are as little of a Christian as possible. They would have moderation in religion! But what is moderation in religion? It is a lie; it is a farce. Doth a wife ask her husband to be moderately loving? Doth a parent expect his child to be moderately obedient? Do you seek to have your servants moderately honest? No! Then how can you talk about being moderately religious? To be moderately religious is to be irreligious. To have a religion that does not enter into the very heart and influence the life, is virtually to have no religion at all. I tremble sometimes, when I think of some of you who are mere professors…How many of you make clean the outside of the cup and platter; and because the church can lay nothing to your charge, and the world cannot accuse you, you think the outside of the cup will be sufficient. Take heed! take heed! The judge will look at the inside of the cup and platter one day; and if it be full of wickedness He will break that platter, and the fragments shall for ever be cast about in the pit of torment…Ah! gilded Christians, beautifully painted, varnished, polished, what will ye do when ye shall be found at last to have been worthless metal? When the wood, hay, and stubble shall be burned and consumed, what will ye do if ye are not the genuine coin of heaven, if ye have not been molten in the furnace, if ye have not been minted from on high? If ye are not real gold, how shall ye stand the fire in that “great and terrible day of the Lord?” ~ C.H. Spurgeon
