Proper attitude toward sin (Jeremiah 7-9)

Jeremiah is affectionately referred to as "the weeping prophet."  While that sounds like a fairly derogatory nickname, I believe it warrants some merit.  Time and time again we have read that Israel strayed far from the Lord, indulging in sin and corruption.  Now Judah was facing certain punishment, and Jeremiah's response was to mourn over the whole situation.  Too often in contemporary Christianity we do not mourn over sin.  We embrace it, we participate in it, and we even condone it; but how often do we mourn over it?  How often do we mourn over the sins that others in our church and fellowship commit?  Jeremiah had it right: he understood the consequences and was therefore saddened by the choices that were made by the people.
