Self-control (Galatians 5:22-23), which is often translated “sober”, is a sober-mindedness that gives thought before acting. Self-control, which is produced by the Holy Spirit, gives way to godly desires rather than sinful desires. A person with self-control looks to future and eternal realities rather than indulging immediate sinful impulses.
So be on your guard, not asleep like the others. Stay alert and be clearheaded. Night is the time when people sleep and drinkers get drunk. But let us who live in the light be clearheaded, protected by the armor of faith and love, and wearing as our helmet the confidence of our salvation
