This document provides a summary of four lessons on wise living based on Ephesians 5:15-21. The lessons are: 1) Make the most of your time, as time wasted can never be redeemed. 2) Understand God's will through prayer, reading the Bible, and obeying it. 3) Be filled with the Holy Spirit rather than alcohol to stay in control. 4) Practice submission to others by humbling yourself as Christ did. Taken together, the lessons teach that wisdom involves using time well for God, discerning and following his will, allowing the Spirit to guide you, and honoring others through service.
