I have a few thoughts on this. First, the author of this article doesn't discuss the scripture in Acts properly. Acts 2:13 (NIV) says "Some, however, made fun of them and said, “They have had too much wine.” I don't know anyone who has ever confused someone speaking in a different language with someone who is drunk. I lived overseas for 8 years and never thought someone speaking German/Italian/Japanese, etc. was drunk because of the language he is using. I think this verse is a clue to the activity that was happening. A few verses later, Peter makes the point that they are not drunk but that what is happening is a result of what Joel prophesied would happen--prophecy, dreams, visions, signs on the earth, etc. Second, I have met Heidi and Roland Baker and I can tell you that what they carry is as real as it gets. When someone has a realization of God's perfect love, it wrecks them. I have spent time in similar situations where I was wrecked by God's love and all I could do was lay on the floor. Third, we have to remember that we serve a supernatural God and we should expect him to act in supernatural ways. I don't want to serve a God that can only do what I expect or understand--he is so much bigger than that. If you want to keep from being deceived, ask God for discernment, that has always worked well for me.
