Should one exercise speaking in tongues?

[Hopeful 2]

Any evidence over the last 100 years when a born again believer starts speaking in a known language foreign to them prior to the regeneration? For example, someone who has never spoken ancient Greek prior to being born again starts speaking it perfectly once regenerated?

I wouldn't know, but my view of the world is small.

Personally, I wish God gave me the ability to speak ancient Greek after being regenerated. That did not happen.

It isn't up to you.
If your turn from sin was real, and you were baptized in the name of Jesus Christ for the remission of past sins,
you will have received the gift of the Holy Ghost.
Tongues is the next sign, for the unbelievers of your conversion.

This question is not meant to downplay speaking in tongues. Every now and often I get the urge to break into a pattern of sound and utterances which was an unknown phenomenon to me prior to regeneration but then I cool down.

If you want the gift, why stop it ?

From 1 Peter 5:8 "Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour." Speaking in tongues is associated with a heightened excited psychological state and one can never be sure that opens the door to a Satanic attack.

Says who ?
Is that written in the bible ?
Or is it from someone who denies the gifts of God ?

Lastly, and most importantly speaking in tongues can be a social equilibrium too in a church setting where some try to appear regenerated by just babbling incoherently.

If there is no interpreter, that is our of line.

I say this...for the true indicator of the Holy Spirit in a faithful in Christ, are the fruits produced; and Paul has told us what they are.

Let God reign in your life, and God will give you all you need.
