The most important thing a pastor does is stand in a pulpit every Sunday and say, 'Let us worship God.' If that ceases to be the primary thing I do in terms of my energy, my imagination, and the way I structure my life, then I no longer function as a pastor.
American culture is probably the least Christian culture that we've ever had because it is so materialistic and it's so full of lies. The whole advertising world is just, it's just intertwined with lies, appealing to the worst of the instincts we have.
If you don't take a Sabbath, something is wrong. You're doing too much, you're being too much in charge. You've got to quit, one day a week, and just watch what God is doing when you're not doing anything.
