Worship Elements: Pleasing to the Lord (Colossians 3:18-4:1)

The apostle Paul exhorts fathers, wives, and bondservants to live out their lives before the Lord’s face.  The Lord does not only exhort adults to life a life pleasing to the Lord, but Paul also exhorts children.  Why would Paul exhort children to obey their parents for that pleases the Lord?  Could there be implications in this exhortation for baptism?
