This sermon addresses the sin of arrogant self-reliance by examining James chapter four, specifically the error of planning life without acknowledging God's sovereignty. The preacher argues that presuming control over time, location, and future outcomes constitutes practical atheism, as it excludes the Creator from daily decisions and business dealings. By referencing Proverbs 16 and the parable of the rich fool in Luke 12, the message highlights human frailty and the certainty that only God knows tomorrow. The central call is to adopt a posture of humility by consistently invoking 'if the Lord wills' in all plans, thereby submitting personal desires to divine direction. Ultimately, trusting God with one's future brings spiritual peace and aligns daily actions with His righteous purposes. What does James 4:13–17 teach about making plans? Is planning for the future wrong? Why does James condemn the businessman in James 4? What is the real sin in James 4:13? What does "If the Lord wills" actually mean? Should Christians literally say "Lord willing" all the time? Is saying "Lord willing" just a religious phrase? How do I know if my plans honor God? What does it mean to submit your plans to God? What is practical atheism? Can Christians live as though God doesn't exist? What does it mean that life is a vapor? Why does James compare life to a mist? How should the brevity of life change my priorities? Who really controls tomorrow? How does pride affect our plans? What is the sin of presumption? What is self-reliance according to James? How does pride lead us away from God? What areas of life should be submitted to God? Is business a spiritual matter? Is work spiritual?
