Yahweh said, "You have been concerned for the vine, for which you have not labored, neither made it grow; which came up in a night, and perished in a night.
      2. From all this we may learn, (1.) That though God may suffer his people to fall into sin, yet he will not suffer them to lie still in it, but will take a course effectually to show them their error, and to bring them to themselves and to their right mind again. We have reason to hope that Jonah, after this, was well reconciled to the sparing of Nineveh, and was as well pleased with it as ever he had been displeased. (2.) That God will justify himself in the methods of his grace towards repenting returning sinners as well as in the course his justice takes with those that persist in their rebellion; though there be those that murmur at the mercy of God, because they do not understand it (for his thoughts and ways therein are as far above ours as heaven above the earth), yet he will make it evident that therein he acts like himself, and will be justified when he speaks. See what pains he takes with Jonah to convince him that it is very fit that Nineveh should be spared. Jonah had said, I do well to be angry, but he could not prove it. God says and proves it, I do well to be merciful; and it is a great encouragement to poor sinners to hope that they shall find mercy with him, that he is so ready to justify himself in showing mercy and to triumph in those whom he makes the monuments of it, against those whose eye is evil because his is good. Such murmurers shall be made to understand this doctrine, that, how narrow soever their souls, their principles, are, and how willing soever they are to engross divine grace to themselves and those of their own way, there is one Lord over all, that is rich in mercy to all that call upon him, and in every nation, in Nineveh as well as in Israel, he that fears God and works righteousness is accepted of him; he that repents, and turns from his evil way, shall find mercy with him.
