Do you know the story behind it? I do. And it is not as crazy as you may think, and far from demonic, just of the flesh, but not in a bad way. It was an "even if God asked me to crawl around on all fours, I would obey." You see a woman had heard God ask her if she would obey Him even if He asked her to look foolish and howl at the moon. So when she got up and told this testimony, she went ahead and howled. From then on in that meeting, and even afterward they all wanted to take part in their confirmation of their obedience to be foolish if God asked. And it was videotaped. I happened to see a longer clip that included the woman. So let's me careful not to judge other's love for God.
Don't forget many times God will see us being too sophisticated in the flesh to even want to speak in tongues, let alone witness to strangers about Jesus. That is one reason, I believe, that tongues has such a bad rep. People can't see themselves being a party to anything that sounds so foolish. They are lukewarm. God wants us to be HOT - all in, not just until it feels uncomfortable. Remember King David dancing before the Lord in his underwear? God loved it, but when his wife mocked him, God struck her barren.
So if you agree and understand. Then stand up and HOWL!!! LOL (I just did, and it felt great!) I think God just chuckled!
