It is amazing. I'm frequently amazed at the statements of people who believe that they are the sole bearer of all knowledge regarding Christianity.
How strange it is. I'll wager that most of those who are extremely dogmatic about something like glossolalia could not find the biblical references used by those to believe that it is a valid part of Christianity.
Yet...they're pleased to tell you that there is nothing to it, and that those who practice is are phonies.
Christianity is such a diverse religion...so many sects and denominations. Very odd.
...The mystery that has been kept hidden for ages and generations.... which is now disclosed...
...The glorious riches of this mystery, which is Christ in you, the hope of glory.
--Colossians 1:26-27 (excerpted /paraphrased)
Much wisdom in your post. Thanks.
