The Christian life must be lived out. It's to go from our head (hear the Gospel), to our heart (God gives us a new heart), to our hands (serve the Lord) and then to our feet (walk in Christ). In Colossians 2:6-15, Paul reminds his readers that since they received Jesus by faith, so too they must walk by faith in His power. We are to continue to walk in Him and to live under His Lordship.
