Third Assurance. Hope assures the soul, that while God stays the performance of one promise, he shall have the absence thereof supplied with the presence of another. And this is enough to quiet the heart of any that understands himself. God hath laid things in such a sweet method, that there is not one point of time wherein the soul of a believer is left wholly destitute of comfort, but there is one promise or other that stands to minister unto his present wants. Sometimes, haply, he may want what he strongly desires, yet even then care is taken for his present subsistence; one promise bears the Christian company while another comes. And what cause hath the sick man to complain, though all his friends do not sit up with him together, if they take it by turns, and never leave him without a sufficient number to look to him?
We read of a ‘tree of life,’ Rev. 22:2, ‘which bears twelve manner of fruits, and yieldeth her fruit every month,’ so that it is never without some hanging on it which is fit for the eater. What can this tree be better conceived to be than Christ, who yields all manner of fruit in his promises, and comfort for all times, all conditions? The believer can never come but he shall find some promise ripe to be eaten, with which he may well stay his stomach till the other—whose time to be gathered is not yet come—hangs for further ripening. Here you see the Christian hath provision for all the year long. When Christ returned to heaven he gave his disciples this to comfort them, that he would come again, and carry them with him unto his father’s house, where no he lives himself in glory, John 14:2, 3. This is sweet indeed. But, alas! what shall they do in the meantime to weather out those many storms which were to intervene between this promise and the time when it shall be performed? This also our Saviour considered, and tells them he does not mean to leave them comfortless, but gives them another promise to keep house with, in the meantime, i.e. a promise of his Spirit—who should be with them on earth, while [until] he took them to be with him in heaven, John 14:16. The Christian is never at such a loss wherein hope cannot relieve it. ‘Blessed is the man that trusteth in the Lord, and whose hope the Lord is, for he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green, and shall not be careful in the year of drought, neither shall cease from yielding fruit,’ Jer. 17:7, 8. These waters are the promises from which the believer draws continual matter of comfort, that as a tree planted by a river flourisheth, however the year goes, so doth he, whatever the temper of God’s exterior providence is. Possibly the Christian is in an afflicted state, and the promise for deliverance comes not, yet then hope can entertain him in the absence of that, at the cost of another promise—that though God doth not at present deliver him out of the affliction, yet he will support him under it, I Cor. 10:13. If yet the Christian cannot find this promise paid into such a height as to discharge him of all impatience, distrust, and other sinful distempers—which to his grief he finds too busy in him for all the promise —then hope hath another window to let out the smoke at, and that is by presenting the soul with those promises which assure the weak Christian that pardoning mercy shall cover those defects which assisting grace did not fully conquer. ‘I will spare them as a man spareth his own son that serveth him,’ Mal. 3:1. So, Micah 7:18‘Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage? he retaineth not his anger for ever.’ And certainly God would not have suffered so much impatience to have broken out in Job, but that he would have something left for pardoning mercy to do at the close of all, to which that holy man should see himself beholden, both for his deliverance, and that honourable testimony also which God himself gave of him before his uncharitable friends, who from his great afflictions, and some discomposure of spirit in them, did so unmercifully burden him with the heavy charge of being a hypocrite.
