He has made the formula so easy that anyone who wants it can have it. It is possible to have revival without music and singing, without taking an offering, even without preaching. But it is impossible to have revival without someone pouring out a burdened heart to God. The common thread through all revivals down through the ages is prayer. In the book of Acts, the disciples gathered in the Upper Room and prayed and tarried.
Prayer is a constant all through the book of Acts.
It could be that we lack spiritual renewal in our day because of a lack of prayer of God's people. If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. The sin unto death is a doctrine that is much misunderstood. But I believe that there is an equally great truth to be found in this verse concerning prayer. God says that if we see a brother sin, we can, through our prayers, restore that brother.
