There is No Sunday "Worship Switch"

R. Kent Hughes, in Worship by the Book (p. 141):

Because worship is a way of life, you cannot worship corporately on the Lord's day if you haven't been worshiping throughout the week--apart from repentance! Christians don't have a Sunday "worship switch," despite what is sometimes portrayed on television. Neither must we be allowed to think that "worship" is only part of the service--as if singing and praise were worship in contrast to the preaching. And "worship leader"? What an odd term! Does the worship end when his or her part is done?
