So the thing that this passage is pointing to has already happened. Read the rest of this chapter-it's an amazing passage of Scripture! We don't need to keep begging the Holy Spirit to fall (unless you want to sell more tickets to yet another conference).
The Holy Spirit has come.
These professional speakers don't want you to know that. They continually tell you that you don't have enough of the Holy Spirit until you buy tickets and go to their events and buy their books and get lulled into a semi-hypnotic state by the soft-rock worship team and then listen to people talk a lot, tell outlandish & unverifiable stories, and twist God's Word while they brag about how humble they are.
By the way, if you're really interested in getting more you can spend an extra $79 for the Premier Ticket to have one "meet and greet session" with a Super Apostle; maybe you'll get an "anointing" or "mantle" or "impartation" or something.
