As in still earlier days, in Genesis xvi. There you are introduced to the domestic arrangement of Abraham’s family as to the servant and her mistress, and their disputes; and yet, in all that, you get the profound mystery of the two covenants. Gal. iv. And again, in the act, the ordinary act, of discharging a servant, another feature in the same mystery is presented to us, in chapter xxi. The wisdom of God delights in these scenes and materials; they rebuke the erring thought of man’s heart, that important things must be done or said by imposing methods--that the prophet must come forth and strike his hand over the place. 2 Kings v. 11. But it is with rude and inartificial instruments that both the wisdom of God and the power of God are commonly seen. Rams’ horns blew down Jericho, and fishermen turned the world upside down, as was said of them. But these homely methods of God’s wisdom aid in carrying the instruction home, and lodging it deep in the intimacies and recollections of the heart. I may therefore still say that Noah’s ship had no pump in it. Indeed it could not. Such a thing would have witnessed against it. God’s provisions would have declared their own insufficiency. That could never have been. God’s provisions and God’s works always tell _whose_ they are by being _what_ they are. Simplicity, and yet sufficiency, give them their character. "Let there be light, and there was light." "Believe in the Lord Jesus Christ, and thou shalt be saved;" and the sinner, believing, rejoiced in God with all his house. So, in like simplicity, in these earlier days. The heart of Noah was not soiled by a suspicion. He rested in the sea-worthiness of his vessel, because of God’s appointment and approval of it--nay, I may say, because of God’s building of it. Faith keeping his heart quiet and assured as to the judgment, hope fills it as to the coming glory. Such is the beautiful way of this "prisoner of hope." _A prisoner of hope_ is one of the Spirit’s titles, I may say, for all the saints of God. Jeremiah was such an one in his day. Jeremiah was shut up in "the court of the prison, which was in the king of Judah’s house," and this, too, for Christ’s sake. He was God’s prisoner, and such an one is always hope’s prisoner. Jeremiah is told to purchase Hananiah’s field, and that was food for hope, like the olive-leaf in the mouth of the dove. It told the prophet of good days to come, though at that moment he was in a prison, the Chaldean army at the city gates, and all the land deserted. The waters were again all around and abroad; but the ark of the prophet, like that of the patriarch, had a window in it.
