These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb. -Revelation 7:14

Dear hearers, have you all got faith? It is, as it were, the key of blessedness. “But all men have not faith,” says the Apostle. Hast thou faith? Dost thou believe in Christ Jesus? In other words, dost thou trust thyself alone with Him? Can you sing with our poet:

“Nothing in my hand I bring
Simply to Thy cross I cling;
Naked, come to Thee for dress,
Helpless, look to Thee for grace.
Foul, I to the fountain fly,
Wash me, Saviour, or I die”?

Make much of the faith that will admit you to heaven… Do any of us want to know what heaven is on earth? Most of us will say, “Aye” to that. Well then, the text tells you how to find heaven on earth. You find it in the same way as they find it in heaven…be thou washed in the blood of Christ, and that will be a great help towards happiness on earth. It will give thee peace now, “the peace of God that passeth all understanding.” Some people think that heaven on earth is to be found in the theatre, and in the ballroom, and in the giddy haunts of fashion. Well, it may be heaven to some, but if God has any love to you, it won’t be heaven to you. Wash your robe, therefore, in the Saviour’s blood, and there will be the beginning of heaven on earth. ~ C.H. Spurgeon
