Scripture:

Romans 12 : 1  Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. ² Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.

John 4:12  Yet a time is coming and has now come when the true worshipers will worship the Father in the Spirit and in truth, for they are the kind of worshipers the Father seeks.

Quotes:

“Worship is the believer’s response of all that they are – mind, emotions, will, body – to what God is and says and does.” 
Warren Wiersbe 

“Worship must be – Christ centered, Holy Spirit led, a Response to the Father, about Intimacy and Service and always lead to Transformation!” 
Tim Hughes 

“Worship is the submission of all our nature to God. It is the quickening of conscience by His holiness; the nourishment of mind with His truth; the purifying of imagination by His Beauty; the opening of the heart to His love; the surrender of will to His purpose – and all of this gathered up in adoration, the most selfless emotion of which our nature is capable and therefore the chief remedy for that self-centeredness which is our original sin and the source of all actual sin”.
William Temple, 1881 – 1944
