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.

If there are problems around us that seem to have defied all efforts to solve them, and if the problems are such that confront us always and which we can't just ignore, then I believe that it's clear that the Lord wants us to have the gift so that we can use it to help humanity to His absolute praise and glory.
