Blessed is the man that hungers and thirst to-day after righteousness, for he shall be filled. -Matthew 5:6

Today, beloved, some of us are hungering after holiness. Oh! what would I not give to be holy, to be rid of sin, of every evil thing about me! My eyes-ah! adieu sweet light, if I might also say, “Adieu sin! “My mouth-ah! well would I be content to be dumb if I might preach by a perfect life on earth! There is no faculty I know of that might not be cheerfully surrendered if the surrender of it would deprive us of sin. But they never thirst for holiness in heaven, for this excellent reason, that they are without fault before the throne of God. Does it not make your mouth water? Why this is the luxury of heaven to be perfect. Is not this-the heaven of heaven, to be clean rid of the root and branch of sin, and not a rag or bone, or piece of a bone of our old depravity left-all gone!- like our Lord, made perfect without spot or wrinkle, or any such thing. And here, too, brethren and sisters, we very rightly hunger and thirst after full assurance and confidence. Many are hungering after it; they hope they are saved, and they thirst to be assured that they are. But there is no such thirst as that in heaven, for, having crossed the golden threshold of Paradise, no saint ever asks himself, “Am I saved?” They see His face without a cloud between; they bathe in the sea of His love; they cannot question that which they perpetually enjoy. So, too, on earth I hope we know what it is to hunger and thirst for fellowship with Christ. Oh! when He is gone from us-if He do but hide His face from us, how we cry, “My soul desires Thee in the night”! We cannot be satisfied unless we have the love of God shed abroad in our hearts by the Holy Ghost. But in heaven they have no such thing. There the Shepherd is always with the sheep, the King is ever near them, and because of His perpetual presence their hungering and their thirsting will be banished for ever. ~ C.H. Spurgeon
