Steven Furtick taught a great sermon on this that you can watch by going to https://www.youtube.com/watch?v=qAQjgpnXj2k
What got me so excited about this sermon is, I always looked at this portion of scripture as adversity that we experience when we serve the Lord. I never looked at this portion of scripture, as us going through things so others can get what they need. This encouraged me that everything is really not about us. When we tell God we will do what ever He asks us to do, He takes us up on it.
So, let me ask you something. What have you gone through that wasn't even about you, and yet you gave the devil credit for it, or worst yet blamed God?
Today we read about Paul and we see what great things he did. Some one, some day, may read about what you did. What will they say?
