There are issues that divide people from one another.  If friends want to stay united they will often avoid these issues.  There are such issues which should not be discussed because their only value is that they divide. 

But there are other issues which naturally divide men one from another yet are essential for our survival.  If we ignore those essential issues it is to our detriment.

Jesus is one of the latter.  He is the least likely to be discussed between friends.  Yet he is the very breath we breathe.  He is the reason that you have a friend at all!  In fact he is the reason that you know what the word friend means.
