Jer 50:4 In those days, and in that time, saith the LORD, the children of Israel shall come, they and the children of Judah together, going and weeping: they shall go, and seek the LORD their God.
"those days" "that time" often are phrases associated with end-of-the-world or end-times occurences. When found here it signifies the duality of the prophecy about Babylon; near (old Babylon) and far (future "Babylon").
Jer 50:6 My people (christians) hath been lost sheep: their shepherds (pastors) have caused them to go astray (false teaching), they have turned them away on the mountains: they have gone from mountain to hill, they have forgotten their resting place (Jesus).
Nowhere is this more evident than in the America today. We are a "christian" nation who have forgotten Jesus and instead are seeking the dollar and prosperity. It is even more evident in that we now have all manner of sinful lifestyle being represented in the pulpit by the very pastors that are supposed to lead the sheep.
They're leading the sheep, all right! Leading them straight to hell! Judgment is coming on America, otherwise God is going to have to beg forgiveness of Sodom and Gomorrah.
