Our Purpose: To Please and Glorify God
To please and to glorify God are a huge part of worship.
To please is personal, and to glorify is to make public. You can please but not glorify, and you can also glorify but not please. We ought to have a relationship with God in the privacy of our lives, and we also should praise Him in the open.
The presence of God comes upon those who please Him, and the power of God comes upon those who glorify Him.
