Here's another thought from A. W. Tozer:
Command those who are rich in this present age not to be haughty, nor to trust in uncertain riches but in the living God, who gives us richly all things to enjoy.
--1 Timothy 6:17
We in the churches seem unable to rise above the fiscal philosophy which rules the business world; so we introduce into our church finances the psychology of the great secular institutions so familiar to us all and judge a church by its financial report much as we judge a bank or a department store.
A look into history will quickly convince any interested person that the true church has almost always suffered more from prosperity than from poverty. Her times of greatest spiritual power have usually coincided with her periods of indigence and rejection; with wealth came weakness and backsliding. If this cannot be explained, neither apparently can it be escaped. . . .
The point I am trying to make here is that while money has a proper place in the total life of the church militant, the tendency is to attach to it an importance that is far greater than is biblically sound or morally right. The average church has so established itself organizationally and financially that God is simply not necessary to it. So entrenched is its authority and so stable are the religious habits of its members that God could withdraw Himself completely from it and it could run on for years on its own momentum. The Warfare of the Spirit, 9-11.
That last part reminds me of a quote I once heard (it may have been Tozer). It went something to the effect of "Remove the Holy Spirit from the early church and everything would have stopped. Remove the Holy Spirit from the church today, and we would go on with business as usual."
