Read Jeremiah 32:37-42

They shall be My people, and I will be their God; then I will give them one heart and one way, that they may fear Me forever, for the good of them and their children after them. And I will make an everlasting covenant with them, that I will not turn away from doing them good; but I will put My fear in their hearts so that they will not depart from Me. Yes, I will rejoice over them to do them good, and I will assuredly plant them in this land, with all My heart and with all My soul.’ “For thus says the Lord: ‘Just as I have brought all this great calamity on this people, so I will bring on them all the good that I have promised them.
