Jeremiah 18:9,10 - Joseph Benson’s Commentary on the Old and New Testaments

If I shall speak concerning a nation to build and to plant That is, To advance and establish all the true interests of it; if it do evil in my sight, &c. If it lose its piety and virtue, and become profane and vicious; then will I repent of the good, &c. I will not proceed with the good work which I was performing in its behalf, but it shall be intermitted; and what favours were further designed it shall be withheld. Thus God changed his purpose concerning Eli's house, 1 Samuel 2:30; and hurried Israel back into the wilderness, when he had brought them within sight of Canaan; and thus he rejected those lost sheep of the house of Israel who refused to embrace the gospel, notwithstanding the general promises he had made to that people, and even after he had sent his Son to seek and save them. In like manner neither can any particular Christians, nor Christian churches, lay any claim to God's general promise of preserving and finally saving them, any further than they keep close to that rule of faith and manners which he hath prescribed to them in the New Testament.
