I don't get the mail everyday at the church property. I look in the mailbox about four out of the seven days. If there is something important for me, or that interests me, I pull it out. Once or twice a week, I take everything out and throw most of it away. I kept the brochure from First Baptist Church of Hammond, titled, "The Great Summer Revival." A big Billy Sunday in traditional pose silhouettes the background. It is the 2017 youth conference, occurring July 18-20.
So, revival will occur. It is planned for July 18-20, not July 16 or June 17. I saved the brochure because this is a common idea. Is it a delineating factor for revivalists? I think so. Revivalists plan revivals. You can make that call, revival will occur, because there is a formula to cause it to occur.
You suggest revival will occur, use upbeat music, pack people into a room to polarize the audience, have a certain style of speaking with a particular kind of invitation, and you can guarantee "revival." Revivalism is a set of practices that produce an atmosphere conducive to professions of faith and decisions of dedication. You can count on revivals to occur with necessary conditions being met.
One of the reasons that the professions and decisions are called "revival" is because they are just professions and decisions. They aren't actual salvation and sanctification. They are experiences primed by manufactured, external stimuli, and labeled some type of work of God. Actual, real results are not expected. This point is built into their plans of salvation and doctrinal statement. No real repentance must occur for the revival of revivalism.
You can plan on something that you can make happen. Since it is you making it happen, know then that it isn't God making it happen. God will do things that are of Him, characterized by Him. The planned revivals of revivalism are made by men, using human techniques. They are not revival.
Revival can occur, but it won't have anything to do with our planning of it. If it does occur, those with whom it does occur will be fully cognizant, clear thinking people. They will hear plain, thorough biblical exposition. They will be good soil, with hearts ready to hear. If the soil on which the seed is cast isn't good, no other factor will change the result.
