Today's reading reminds me again of the many times the Jews rejected God's protection and guidance and revert (again) to idol worship, murder and breaking other of the Ten Commandments. I always say to myself (like I haven't seen the end of the movie) "they are going to stop that at some point, right."
But I know that there are ways I can serve better, learn more and share Christ more in my daily life that I put aside or put off.
Interestingly, Jeremiah is told by God to warn the people of the coming discipline but don't expect any one to heed the warning. A whole town and no one is persuaded. But he still must because God said to. We should know that when we speak about Jesus there could be a whole city not listening, but we have been told to share the Good News.
