The night is nearly over; the day has drawn near. So let us lay aside the deeds of darkness and put on the armor of light. — Romans 13:12

The night is far spent, the day is at hand — put on the armor of light. What's the armor? Put on the Lord Jesus Christ. That's it. You don't arm yourself with resolutions and self-improvement; you clothe yourself with Christ, counting everything else as rubbish. Walk as children of light, because the One who is light has already won.
