The Nature of Worship

In preparation for next week's message, I have been reviewing my notes from Ecclesiology. Dr. James R. Mook stated many years back, "Worship must begin in a person's spirit and be done without hypocrisy and be done with uncompromising acceptance of God's revelation of Himself in Scripture." (Ecclesiology, The Local Church Part 2: The Purpose of the Local Church, page 6) He used John 4:23-24 to make this point. Just prior to that statement, Dr. Mook used Romans 12:1-2 to teach that worship is the sacrifice of one's entire self as a living sacrifice.

I have been chewing on these two points and realize how far short I, and probably many others fall. This failure leads me to ask a few questions: 1) If we fall short of an entire self-sacrifice have we then truly worshipped? 2) If we have yet to master our hypocrisy and fail to yield to God's revelation in Scripture, have we truly worshipped God? 3) If questions 1 & 2 are a "yes" then what have we done?
I am going to ponder these questions for a few days before I attempt to answer them. However, I would appreciate your insights.
