17 Isn’t it wheat harvest today? I will call to Yahweh, that he may send thunder and rain; and you shall know and see that your wickedness is great, which you have done in the sight of Yahweh, in asking for a king.” 18 So Samuel called to Yahweh; and Yahweh sent thunder and rain that day: and all the people greatly feared Yahweh and Samuel. 19 All the people said to Samuel, “Pray for your servants to Yahweh your God, that we not die; for we have added to all our sins this evil, to ask us a king.” 20 Samuel said to the people, “Don’t be afraid. You have indeed done all this evil; yet don’t turn aside from following Yahweh, but serve Yahweh with all your heart. 21 Don’t turn aside; for then you would go after vain things which can’t profit nor deliver, for they are vain. 22 For Yahweh will not forsake his people for his great name’s sake, because it has pleased Yahweh to make you a people to himself. 23 Moreover as for me, far be it from me that I should sin against Yahweh in ceasing to pray for you: but I will instruct you in the good and the right way. 24 Only fear Yahweh, and serve him in truth with all your heart; for consider how great things he has done for you. 25 But if you shall still do wickedly, you shall be consumed, both you and your king.”

Commentary on 1 Samuel 12:16-25
(Read 1 Samuel 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.
