17 It's summer, as you well know, and the rainy season is over. But I'm going to pray to God. He'll send thunder and rain, a sign to convince you of the great wrong you have done to God by asking for a king." 18 Samuel prayed to God, and God sent thunder and rain that same day. The people were greatly afraid and in awe of God and of Samuel. 19 Then all the people begged Samuel, "Pray to your God for us, your servants. Pray that we won't die! On top of all our other sins, we've piled on one more - asking for a king!" 20 Samuel said to them, "Don't be fearful. It's true that you have done something very wrong. All the same, don't turn your back on God. Worship and serve him heart and soul! 21 Don't chase after ghost-gods. 22 There's nothing to them. They can't help you. They're nothing but ghost-gods! God, simply because of who he is, is not going to walk off and leave his people. God took delight in making you into his very own people. 23 "And neither will I walk off and leave you. That would be a sin against God! I'm staying right here at my post praying for you and teaching you the good and right way to live. 24 But I beg of you, fear God and worship him honestly and heartily. You've seen how greatly he has worked among you! 25 Be warned: If you live badly, both you and your king will be thrown out."

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.
