I'm going to go out on a limb. As I said in an earlier post, I think the church advances in waves and that we in the North American church are currently in a trough.
But what will the next wave be like? I'm going to make a prediction. I think the next revival will retrieve something of the sense of the awesomeness of God. I think a proper sense of awe has generally been lost. We think of God as our pal, not as our King, not as the great Creator above all the heavens, not as the one the very thought of whom should take our breath away.
I hope we don't loose the sense of God being our close friend, but if we can recover the awe, I think we'd be better off.
If I'm right, perhaps church services will be marked with more formality as people act in ways they think are respectful of God. Casual will be out and clerical collars and candles and old hymns and "Sunday clothes" will make a comeback, which is pretty much fine by me... except for ties; I really don't want to wear ties.
