Tozer’s theory of Spirit filling was deficient in certain ways. But the following statement rings true, and what it talks about hasn’t got any better just because the styles have changed.

Then, also, the Spirit gave a bright, emotional quality to their religion, and I grieve before my God over the lack of this in our day. The emotional quality isn’t there. There is a sickliness about us all; we pump so hard trying to get a little drop of delight out of our old rusty well, and we write innumerable bouncy choruses, and we pump and pump until you can hear the old rusty thing squeak across forty acres. But it doesn’t work.
