A couple of decades back I attended a small Charismatic church revival in which Jesse Duplantis was preaching. I was open-minded to the possibility that it was genuine at the time and I went forward with a specific problem to pray about. No one ever asked what my prayer concern was. The preacher anointed me with oil and laid hands on me but in spite of the pushing and the mighty exhortations to surrender, I did not fall out. I was not being stubborn, nor was I there to prove anyone wrong. In fact I made a point of surrendering to whatever the Holy Spirit chose to do and thus not resisting, but I was not going to fake anything either.
That said, there have been times at an Alter where God answered prayers in startling fashion. One example is about a year prior to that I was instantly healed of a very fresh nervous breakdown when a dear Elder who I know is a sincere man of God prayed for me and with me. But I have never been “slain in the spirit” and even when I was a Pentecostal I saw it an unnecessary and unfortunate diversion from what our focus should have been during those times of prayer. And yes, God has answered prayers in less instant fashion though just as startling, after praying and surrendering issues at a Baptist “alter”.
