This sermon is from James 4:1-11. Lots of people are familiar with parts of the passage but almost every time I hear it preached they pull it to pieces. People talk about quarreling and such or talk about praying, but I find it particularly interesting that James puts the verse "You don't have because you don't ask and when you do as you are with the wrong motives wanted to have for yourself." (NTGV) right in the middle of a discourse on quarreling so it seems to me that these thoughts are intertwined.
Give it a listen to find out why we should all be working together and how we can be more effective by asking the right questions.
