We can walk worthy of the Lord unto all pleasing. As born again believers, walking worthy of the Lord means living in such a way that the privilege granted to us of being a child of God is being exhibited to the world. Also, we should, as this scripture points out, be "increasing" in the knowledge of God. How do we increase in the knowledge of God? Increase in the knowledge of His Word. As we do this, we will be walking worthy of the Lord, pleasing Him.
