And more must be done even after we are securely fitted into our place. Stones often look well enough when first built in, but soon lose their colour; and their surface and fine edges crumble and shale off, so that they need to be constantly looked to. So do the stones in God's temple get tarnished and discoloured by exposure. One sin after another is allowed to stain the conscience; one little corruption after another settles on the character, and eats out its fineness, and when once the fair, clean stone is no longer unsullied, we think it of little consequence to be scrupulous. Then the weather tells upon us: the ordinary atmosphere of this life, with its constant damp of worldly care and its occasional storms of loss, and disappointment, and social collisions, and domestic embroilment, eats out the heavenly temper from our character, and leaves its edges ragged; and the man becomes soured and irritable, and the surface of him, all that meets the casual eye, is rough and broken. Above all, do not many Christian persons seem to think it enough to have attained a place in the building, and, after spending a little thought and trouble on entering the Christian life, take no step onwards during the whole remainder of their lives? But it is in God's building as in highly ornamented buildings generally. The stones are not all sculptured before they are fitted into their places; but they are built in rough-hewn, so that the building may proceed: and then at leisure the device proper to each is carved upon it. This is the manner of God's building. Long after a man has been set in the Church of Christ, God hews and carves him to the shape He designs; but we, being not dead, but living, stones, have it in our power to mar the beauty of God's design, and indeed so distort it that the result is a grotesque and hideous monster, belonging to no world, neither of God nor of man. If we let a thousand other influences mould and fashion us, God's design must necessarily be spoiled.
