Jeremiah 21:8-9 And unto this people thou shalt say, Thus saith the LORD; Behold, I set before you the way of life, and the way of death. (9) He that abideth in this city shall die by the sword, and by the famine, and by the pestilence: but he that goeth out, and falleth to the Chaldeans that besiege you, he shall live, and his life shall be unto him for a prey.
The prophet Jeremiah is giving a Divine Warning to the King of Jerusalem and his people. They have two choices before them: one leads to life, and the other leads to death. But there is no standing still, there is no wavering. Choose, and choose quickly, the path that you will take.
In a very real way, the same choice is before us today in regards to salvation: chose to stay in the city (sin) and die an everlasting death of separation and punishment in Hell and the Lake of Fire. Or, leave the city (sin) and fall on the Lord for his mercy and grace. The Lord has given the warning and the choice is yours to make.
