12:22 For the LORD will not forsake his people for his great name's sake: because it hath pleased the LORD to make you {n} his people.
(n) Of his free mercy, and not of your merits, and therefore he will not forsake you.
12:22 His name's sake - That is, for his own honour, which would suffer much among men, if he should not preserve and deliver his people in eminent dangers. And this reason God alledgeth to take them off from all conceit of their own merit; and to assure them, that if they did truly repent of all their sins, and serve God with all their heart; yet even in that case their salvation would not be due to their merits; but the effect of God's free mercy. To make - Out of his own free grace, without any desert of yours, and therefore he will not forsake you, except you thrust him away.
12:16-25 At Samuel's word, God sent thunder and rain, at a season of the year when, in that country, the like was not seen. This was to convince them they had done wickedly in asking a king; not only by its coming at an unusual time, in wheat harvest, and on a clear day, but by the prophet's giving notice of it before. He showed their folly in desiring a king to save them, rather than God, or Samuel; promising themselves more from an arm of flesh, than from the arm of God, or from the power of prayer. Could their prince command such forces as the prophet could do by his prayers? It startled them very much. Some will not be brought to see their sins by any gentler methods than storms and thunders. They entreat Samuel to pray for them. Now they see their need of him whom shortly before they slighted. Thus many who will not have Christ to reign over them, would yet be glad to have him intercede for them, to turn away the wrath of God. Samuel aims to confirm the people in their religion. Whatever we make a god of, we shall find it deceive us. Creatures in their own places are good; but when put in God's place, they are vain things. We sin if we restrain prayer, and in particular if we cease praying for the church. They only asked him to pray for them; but he promises to do more, to teach them. He urges that they were bound in gratitude to serve God, considering what great things he had done for them; and that they were bound in interest to serve him, considering what he would do against them, if they should still do wickedly. Thus, as a faithful watchman, he gave them warning, and so delivered his own soul. If we consider what great things the Lord hath done for us, especially in the great work of redemption, we can neither want motive, encouragement, nor assistance in serving him.
