But by far, the “open up the Heavens” slogan is one of the more popular mottos of unbelief today, accompanied by obligatory groans, pleas and mournful entreaties. It sounds like a romantic request indeed, but it is an accomplished one. Opening and closing the heavens is not an on again, off again affair. “Last week, when our worship leader hit that one chord on the guitar, the Heavens opened up!” Wow. All we needed was a guitarist I suppose! If Jimi Hendrix had come a little earlier, perhaps Jesus didn’t need to die after all? I don’t deny that you had a good service and that people felt the Glory. But in reality, the Glory of God was already there. You just became aware of it. God’s heavenly presence is not a fleeting, or gradually oncoming thing that is subject to the whim of the congregation’s mood. In fact, the Bible never even says that His Glory is a future-coming thing. It’s already here.
Some people think that one day His Glory – His manifest presence – will cover the Earth as the waters cover the seas. That’s a misquote of Habakkuk 2:14, which actually says that the “knowledge” of the Glory will one day cover the Earth… Instead, read Isaiah 6:3 which says that Heaven and Earth are right now full of His Glory. The Glory is here, but one day the whole Earth will be aware of it!… You will not live a consistent, daily life of open heavens reality if you can’t acknowledge that you are in perma-glory.

I agree with what John Crowder says, except that the Holy Spirit does seem to make His Presence known, often, in waves, in a corporate setting especially. This happens in worship. He is a Person, after all, and not a static presence. Love that about Him.
