We live in a very self-centered world. Well the bad news is that it is not all about you. Every breath you take, every sunrise you witness is because of God's great faithfulness, mercy and grace. The purpose of our lives is not self but obedience to God. God is not thinking whether the task he has given you is worthy of your time, he is not considering how you feel about it, he is doing it for his glory. The end results is that God is glorified, and in that we find peace for it is always for our good.
