I believe that the church can use the gift of praying in tongues (glossolalia) to make great scientific discoveries, solve economic problems, eradicate illiteracy and poverty, etc.

Tongues are the divine secret codes (passwords, keys) to God's secret solution to the world's problems.

@Chidiotamiri Wow.
Certainly the gift that you describe is NOT the gift the Bible speaks of but a counterfeit.

Read the Word. It's pretty clear what the 'biblical' gift of tongues is for - and what it is NOT for.

@erdenpilger
Thanks for your opinion. But the Bible says that when we pray in tongues, we're speaking mysteries. Also note that those mysteries have interpretations (the gift of the interpretation of tongues).

But what are those mysteries? Are they just abstract heavenly mysteries that don't have any earthly relevance? Or are they only religious mysteries that are only applicable within the four walls of a local church?

Don't you think those mysteries, when decoded or interpreted, have to do with the mission of the church on earth?

Does the church have a role to play in entertainment, economy, health, education, politics, business, family, military, etc.?

Don't you think that by praying in tongues heavenly principles on how to establish God's kingdom on earth can be unveiled through us?

Meanwhile, I'm speaking from experience, not mere theory, of the great blessings I've received through praying in tongues.

@Chidiotamiri I'd like to stick to what the Bible says and not peoples 'experience'.

Mysteries are called mysteries for the reason that the person speaks things in a language unknown to him/herself. That should be evident.

It doesn't have anything to do with politics, science or other worldly activities you mention. It it for HIM. Not for US.

Stick to what is written, that's my humble advice to you.
