The same question can be politely turned around: Please prove that it is not.
1 Corinthians shares that tongues were a normal part of a church.
Now, Corinth was not a very healthy church, so Paul had to give them some specified instruction. So many today will take that fact and then make a logical fallacy out of it: "Because Corinth used tongues inappropriately and had problems, therefore tongues are not for today."
According to the NT, supernatural gifts were a normal part of church life. Now, the common idea today is that because we have the Bible, we no longer need supernatural gifts like tongues and prophecy, but... chapter and verse, please.
And yes, I know about the argument that uses 1 Cor. 13:9-13 as it's base, but let's be VERY careful in how we use that passage...because if you take that logically, you are saying if "that which is perfect" is the Bible, then not only do TONGUES and PROPHECY cease, but also KNOWLEDGE... It just doesn't make sense to me at all...
Besides that, the Bible is not perfect. It's original manuscripts were God-breathed, but not every single period and comma is now in the perfect spot--scholars had to made educated guesses--so we can say it's
darn near perfect and very very trustworthy, worthy of serious study and meditation because God's words are on those black-and-white pages... but it is NOT perfection. GOD is perfection.
One other logical fallacy that is commonly made: "I see major nasty things in the Charismatic movement, and/or I've seen people grossly misuse so-called 'spiritual gifts,' so therefore there are not actual God-given supernatural spiritual gifts today."
Another illogical conclusion: Lots of people (on TV, in crazy pentacostal churches, whatever) claim they have spiritual gifts but it doesn't feel like it's really God--or they use them as a means to get more money from viewers, or just have a really nasty spirit about the way they do everything...
Well, the fact that there
is a lot of demonic and fleshly misuse/counterfeit going on does
not mean you throw out the baby with the bathwater. There are plenty of Christian sects that are SO off-base (we can all think of plenty right off the top of our heads--Mormonism, Jehovah Witnesses, etc..), but that in no way "proves" that Christianity itself is wrong. You see my point.
One other important thing to remember is the Corinthians themselves are living proof that supernatural spiritual gifts CAN be mis-used, and are NO indicator of spiritual maturity. They are supposed to help the Body of Christ grow into the Head (Eph.4), however babes do not always 'get' that, and if they do not have mature leaders, they'll use their gifts in fleshly ways.
Anyways... I'd recommend this:
Read 1 Corinthians with an open heart,
willing to be shown that supernatural gifts ARE for today (if Yahweh really does think so)...
You may be surprised! :o) Ephesians 4 and Romans 12 are other great ones--supernatural gifts (like prophecy, etc...) are considered a normal and healthy part of a growing Body...
