This sermon meditates on James 4:13-17, challenging believers to examine their attitudes toward planning and the future. The central argument is that human life is transient, described as a vapor that appears briefly and then vanishes, which should humble the heart against the arrogance of presumptuous boasting. While planning and business are not inherently sinful, they become evil when driven by pride rather than a recognition of God's sovereignty. The text urges believers to adopt a posture of submission, acknowledging that only God knows what tomorrow holds and that all actions should be contingent upon His will. This attitude of humility is contrasted with the sin of omission, where knowing the right course of action but failing to submit one's life to God constitutes a failure in duty.
