Jeremiah chapter 51 verses 38 - 41

"They shall roar together like lions; they shall yell as lions' whelps. In their heat I will make their feasts, and I will make them drunken, that they may rejoice, and sleep a perpetual sleep, and not wake saith the Lord. I will bring the down like lambs to the slaughter, like rams with the he goats. How is Sheshach taken! And how is the praise of the whole earth surprised! How is Babylon become an astonishment among the nations".
"Sheshach" is yet another symbolic name for Babylon, as are Merathaim and Pekod. Just as Jesus was led as a lamb to the slaughter so shall everyone be led who rejects him. Even as we are "accounted as sheep for the slaughter" (Rom:8:36), so shall those who slaughtered us be slaughtered. "And as ye would that men should do to you, do ye also to them likewise" (Lk:6:31). Yea, though they roar like lions they shall be led as lambs. Always call the devil's bluff for he walketh about as a lion, seeking whom he may devour, yet he is not a lion, merely as, or like a lion and he may not devour true, Holy Spirit filled christians and even if he does devour someone, they may yet be delivered out of his mouth. He is again seeking to mimic Jesus who IS THE LION OF JUDA, who when he devours, none may recover.
Verse 39 reminds me of this passage from Romans - "Wherefore God also gave them up to uncleaness through the lusts of their own hearts" (1:24) and verse 28 - "God gave them over to a reprobate mind". Like Pharaoh, God hardens an already hardened heart, knowing all the while they that are his, knowing who will repent and who will not. We must be led by the Spirit in all we say and do, especially when we are evangelizing. You don't want to waste the Gospel on someone God has given over to a reprobate mind, someone God has forsaken. Only the Holy Spirit knows the difference. I've recently come up with a word to describe people who choose to go to Hell instead of Heaven. I call them "Hadists". It's a cross between "Sadist", people who like pain, and "Hades", the Greek word for Hell. When witnessing to someone, if they reject the Gospel, you can use my word. Say to them, "Oh I see, so you're a Hadist". When they say what? Say, "You're someone who would rather go to Hell than Heaven, who WANTS TO GO TO HELL". Let the Holy Spirit lead you in all you do. He will witness to those who reject him because he still loves them but make sure he's the one leading you to do so. If God puts them in a perpetual sleep, if he makes them "feast and become drunken that they may rejoice", far be it from us to wake them up. Like Nabal, who "held a feast in his house like the feast of a king; and Nabal's heart was merry within him for he was very drunken" (1 Sam:25:36), they, the world, all who dwell in Babylon are completely unaware of their impending doom. For the very next day, the very heart of Nabal that was merry, turned to stone and ten days later he died for THE LORD smote him. Even as the phillistine's hearts were merry and they called for Samson to mock him and his God, then sudden destruction came upon them all, so shall it be with Babylon. Even as they are worshipping their god in their temple, in their bodies, death will surprise them. Then death will not be their end, but the beginning of eternal torment. "As it was in the days of Noah..." (Lk:17:26).
