Actually, I don’t know that many do much rolling around nor writhing though it does occur on occasion and has even been somewhat experienced by me in some respects.
Most folks find it strange and unfathomable because they have never even bothered to be that concerned about God—much less in anguish before Him over their sins or that desperately wanting MORE OF HIM or that desperately NEEDING HIS TOUCH etc.
So, in their ignorance and haughtiness, they find it easy to mock and be derisive.
I doubt God’s that pleased with such an attitude.
I doubt God is pleased with people who think they know him so well.
