Just like the people, in that day, it is the same today, people just paid no attention. The people in Jeremiah's time did not seek out the ways of their leaders of the past. Godly leaders such as Moses, Joshua, David, Hezekiah, or Josiah. They continued in their sins and listened to false prophets declaring peace and safety (Jeremiah 6:13-15). We have the same today in America. We have preachers that no longer preach about the atoning blood of our savior, instead it is a prosperity message, a message of appeasement for the homosexuals, and a anything goes message because God is Love. We even now have preachers that stand behind the sacred desk and say that Jesus is not the only way. God forbid! The twelve step program is not the way, Mohamed is not the way, Buddha is not the way, there is only one way and that is Jesus!
Please let me make this point: Just because something is new, it is not always wrong, but whatever is "new" should not diminish or take away the practice of the past faith, the faith of our fore fathers in the church. Modern day Christians must keep and share the same faith and practice that faith just like the first century Christians did. Let us strive, then, to seek the old paths and remain within them, so that we may obtain the Promised Land and not find ourselves separated from God!
