III. Those that come into the church shall be welcome; for so spacious is the holy city that though, Lord, it is done as thou hast commanded, yet still there is room. "Therefore thy gates shall be open continually (v. 11), not only because thou hast no reason to fear thy enemies, but because thou hast reason to expect thy friends." It is usual with us to leave our doors open, or leave some one ready to open them, all night, if we look for a child or a guest to come in late. Note, Christ is always ready to entertain those that come to him, is never out of the way, nor can they ever come unseasonably; the gate of mercy is always open, night and day, or shall soon be opened to those that knock. Ministers, the door-keepers, must be always ready to admit those that offer themselves to the Lord. God not only keeps a good house in his church, but he keeps open house, that at any time, by the preaching of the word, in season and out of season, the forces of the Gentiles, and the kings or commanders of those forces, may be brought into the church. Lift up your heads, O you gates! and let such welcome guests as these come in.
