I think a lot of things in the Bible are "true" but not in the literal way I think of them. Those before us without our knowledge of how some things worked had a different way of expressing the way things seemed to them.

I don't believe the Gift of Tongues was necessarily instantaneous learning of another language but someone who had a Gift for languages and learned another language quickly, either before or after going to another land for the Church. I think the Tower of Babel was a "representation" of how things must have appeared to have happened, an "instanteous" shortcut story like the seven days of Creation or the 40 days/40 nights of the Flood, etc. I believe there were certainly floods but not one, single one that covered the entire Earth, just that portion of the Earth the Biblical writers knew/cared about. It makes sense to me to represent the "reverse" of the Tower of Babel (first Gift of Tongues) in the same way. I don't think the Sun actually stood still at Jericho, just time seemed to pass so quickly it appeared to stand still (and would be Earth not rotating in any event). The Bible isn't a book of science and doesn't claim or need to be. That doesn't negate the Truth of what it has to say, just the literalness.

I know there are still people today that have the gift of languages, speak another or many fluently, etc. and I'm sure churches need/hire many of those people as missionaries. But I think a lot of churches don't "concentrate" on the Gifts of the Spirit like was done in the past because the World has gotten more complicated technologically and the "Wow factor" in some of the old stories has faded. So while people still have Gifts of the Spirit, I don't think that they are focused on in the same way anymore.
