Paul's guidance in Ephesians 5:15-21 teaches us to walk in wisdom by paying careful attention to how we live. This means making the most of every opportunity in evil days, understanding God's will through Scripture and prayer, and being filled with the Spirit rather than worldly influences. Walking wisely involves worship that transforms our minds, practicing thankfulness in all circumstances, and submitting to one another in Christ-like humility. By focusing on these principles, we can use our limited time on earth for eternal purposes, helping others come to saving faith in Jesus.
