Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him…
Your heart is a house with many rooms; one apartment is decorated for the occupancy of pride; in another one covetousness may keep its iron safe; on the walls of another, perhaps, sensuality has hung some pictures that, if Christ enter, must be pulled down. Unbelief has chilled and darkened the whole house. Satan has a mortgage on the whole of it, and by and by will foreclose it. An enormous amount of sin has accumulated in every room and closet, for you have never had a "house-cleaning" since you were born. To that dwelling-place of sin, which may yet become a dwelling-place of endless anguish, my loving Saviour has come again. If you will stop the turmoil of business, or the noise of merriment long enough to listen, you will hear a marvellously sweet voice outside, "Behold, I stand here and knock; if thou wilt open this door I will come in." Christ without means guilt; Christ within means pardon. Christ without means condemnation; Christ within means salvation. Christ shut out means hell; Christ admitted is the first instalment of heaven.
(T. L. Cuyler, D. D.)
