I wonder why...

Why do we struggle so much to live in community with some brothers and sisters? What is it that keeps us from loving all unconditionally? Why can't we seem to get over the obstacles of self? Why does it seem everytime we make some progress that very quickly everything falls apart? Why do we run when we get too uncomfortable? Why do we seek comfort more than anything else in the world? Why is it that when you seek the good of others, you then begin to doubt your thoughts all together? Why? Ephesians 6:10-18
