Here are a couple thoughts I have on this topic, taken from 1 Corinthians 12.
In 1 Corinthians 12, the stage is set by v.3: "Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Ghost."
In verse 4-6, Paul explains that different people have different gifts of the Spirit, but they all come from the same Spirit.
In verse 7, he says that each believer gets the manifestation (appearing) of the Spirit, for the improvement of all.
In verses 8-10, he explains what some of these gifts are: word of wisdom (wise counsel), word of knowledge (knowledgeable counsel), faith(!), gifts of healing, working of miracles, prophecy, discerning of spirits (ability to judge), various kinds of tongues (speaking in tongues), and interpreting of tongues. Notice that the people who claim speaking in tongues is THE manifestation of the Spirit believe that if you have the Spirit of God, you must speak in tongues.
But Paul lists speaking in tongues mixed in with other gifts, including faith. Why does nobody say that faith is the primary gift of the Spirit? It seems to me that if any gift is given to everyone, it should be this one. If speaking in tongues would be the first and foremost gift, it should be at the top of the list, and he would give that in verse 7 as the evidence that a person is Spirit-filled.
In verse 11, he re-emphasizes that all these gifts are done by the same Spirit, and that He (the Spirit) gives gifts to believers as He wills.
Jumping down to verse 17, Paul points out that just as different members of a body have different functions, different members of the Body of Christ have different functions.
In verse 28-30, this point is re-emphasized again.
How could a body survive if every limb were a leg? But this is what people are trying to do when they insist that we all need to speak in tongues.
The argument I have heard goes like this: "On the day of Pentecost, they were all given the gift of tongues. Therefore, we should all speak in tongues once we have the Holy Spirit."
Really? Then why did Paul say, "And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues." Should we expect to all be apostles, prophets, and teachers then too? Notice that whenever this topic comes up in the New Testament, it's always "as the Spirit gave them utterance" or "as He wills", never "as they desired" or anything similar.
Another thing, some of these gifts (the word of wisdom, the word of knowledge, faith, etc.) require personal development on our part- it's not necessarily just something God dumped on him one day. David Bercot did not just wake up one day and discover he could accurately describe what the early Christians could say on any one topic. Neither did Lynn Martin just magically learn to describe in detail all the arguments the Catholic and Eastern Orthodox come up with.
These things take study and self-discipline. Is it possible, then, that speaking in tongues is sometimes simply a gift to learn languages?
My conclusion then, is that these gifts could still be around today. Not that everyone has all of them, or that we should necessarily expect a certain gift, but we should be open to the possibility. There are instances, I know, where unusual miracles have been performed even in our times, but it's always as God wills.
