We have here Jeremiah's prayer to God upon occasion of the discoveries God had made to him of his purposes concerning this nation, to pull it down, and in process of time to build it up again, which puzzled the prophet himself, who, though he delivered his messages faithfully, yet, in reflecting upon them, was greatly at a loss within himself how to reconcile them; in that perplexity he poured out his soul before God in prayer, and so gave himself ease. That which disturbed him was not the bad bargain he seemed to have made for himself in purchasing a field that he was likely to have no good of, but the case of his people, for whom he was still a kind and faithful intercessor, and he was willing to hope that, if God had so much mercy in store for them hereafter as he had promised, he would not proceed with so much severity against them now as he had threatened. Before Jeremiah went to prayer he delivered the deeds that concerned his new purchase to Baruch, which may intimate to us that when we are going to worship God we should get our minds as clear as may be from the cares and incumbrances of this world. Jeremiah was in prison, in distress, in the dark about the meaning of God's providences, and then he prays. Note, Prayer is a salve for every sore. Whatever is a burden to us, we may by prayer cast it upon the Lord and then be easy.
