The prophet Jeremiah lived in perilous and strange times, just like we do. He was elected and sanctified and appointed prophet by God unto the nations, foremost to Judah but also to the neighboring nations. Jeremiah lived in times of great apostasy, just like we do. Judah had forsaken the LORD, the covenant, the Law and God sent Jeremiah to tell the people that if they did not return to the LORD, the covenant and the Law that God would have to forsake them and to punish them by Nebuchadnezzar, the Chaldean king. They would have to return to the LORD, and to stop shedding innocent blood, stop with their adultery, stop with their idolatry; “For thus saith the LORD to the men of Judah and Jerusalem, Break up your fallow ground, and sow not among thorns. Circumcise yourselves to the LORD, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem: lest my fury come forth like fire, and burn that none can quench it, because of the evil of your doings” (Jer. 4:3-4). Judah did not hearken to the LORD, they did not return to the LORD, they did not stop shedding innocent blood, they did not stop with their idolatry, they did not stop with their adultery, so the LORD punishes them as promised by carrying them away to Babylon for seventy years. When reading the book of Jeremiah, it is very clear that his message is very timeless, one could believe that Jeremiah could stand here in contemporary Christianity in the end of 2022 and preach the same message, it would fit right in. We have forsaken the LORD and we have forsaken his Word. This is our greatest sin, and if we do not repent and return to the LORD and his Word the same fate will befall us. At least in Sweden has contemporary Christianity shown its contempt for God’s Word, and a great apostasy is lingering showing its face everywhere. God’s Word is denied, the order of creation is denied, no clear teaching is at all on the horizon. And they laugh to scorn any message of doom and judgment. I have therefore written this book, hoping to wake up an disobedient Christianity.
