Christ followers walk in love and express the light of God. Paul compares the relationship between a husband and wife to that of Christ and the church. Children should honor their parents. Fathers should be consistent and clear in leading and teaching their children. One who serves another should serve as to the Lord. One who is served must remain humble, remembering that he and his servant are both accountable to God. Put on the armor of God to prepare for spiritual battles and attacks from the devil. Paul asked the church to pray for him to be bold in proclaiming the gospel. Paul sent word through Tychicus of his progress in ministry.
