The Sin of Arrogance, Part 1 – James 4:13-17. Have you ever become confident about your ability to carry out your plans and make a profit? Do you ever live a “no margin” life? If so, you may be committing the sin of arrogance! James, in his practical way, reminds us that our lives are like a vapor, or like the grass of the fields. We are to measure our life on God’s purpose, not our own agenda!
