When I stopped and thought about what my goal as a Christian is: Everything I do and say is to glorify God. To Glorify God, means to follow the wisdom of Jesus Christ. And to do this, what happens now, in this life, is not meant to be personal.
So, quit taking everything so personal, realize the more you glorify God, the more treasures in heaven you store. When it is not personal, it seems easier, doesn't it?
