A.W. Tozer's The Pursuit of God is one book I cite frequently in regards to work being a way to worship. I recently subscribed to a daily email called Tozer on Christian Leadership that includes quotes from other Tozer works on work as worship. A couple really hit me this week, and I used one in the devotional that I lead my MBA students in on Monday nights (emphasis mine):
"So I've got to tell you that if you do not worship God seven days a
week, you do not worship Him on one day a week. There is no such thing
known in heaven as Sunday worship unless it is accompanied by Monday worship and Tuesday worship and so on....
come into God's house and say, "The Lord is in His holy temple, let us
all kneel before Him." Very nice. I think it's nice to start a service
that way once in a while. But when any of you men enter your office
Monday morning at 9 o'clock,
if you can't walk into that office and say, "The Lord is in my office,
let all the world be silent before Him," then you are not worshiping the
Lord on Sunday. If you can't worship Him on Monday you didn't worship Him on Sunday. If you don't worship Him on Saturday you are not in very good shape to worship Him on Sunday. "Tozer on Worship and Entertainment, 9,24.
"You can worship God at your desk, on an elevated train, or driving in
traffic. You can worship God washing dishes or ironing clothes. You can
worship God in school, on the basketball court. You can worship God in
whatever is legitimate and right and good....
So that's all right.
We can go to church and worship. But if we go to church and worship one
day, it is not true worship unless it is followed by continuing worship
in the days that follow." The Tozer Pulpit, Volume 1, 51-52.
