11-01-15. Phil 1:19-30. There are four common barriers to joy/happiness. Paul experienced all four. He has every reason to be bitter, unhappy and depressed, instead he writes about how to be happy and reflect positively on the Lord, no matter what happens. Paul doesn’t just tell us how to overcome the common barriers to happiness, he shows us by modeling four habits he’d developed. Having looked at two of these habits in the previous sermon we look at the other two in this sermon: 3.Trust God to work things out. & 4. Focus on your purpose, not your problem.
