Another Tongues Discussion

OK, so to just add one more dimension to this conversation let me propose this conversation.

Is there an expression of "tongues" beside the public gift of tongues? In other words, in 1 Corinthians 12 & 14, Paul talks about the necessity for an interpreter when the gift of tongues is used (obviously referring to its use in a public gathering of people with spiritual gifts) (see 1 Corinthians 14:27-28). Also, in 1 Corinthians 14:14 he calls speaking in tongues without an interpreter praying with your spirit which only edifies yourself and God. In Ephesians 6:18, Paul instructs believers to continue praying "in" the Spirit for a number of needs. Some believe that there is a spiritual gift of tongues for use in gatherings of believers and a private expression of union with the Holy Spirit expressed in a "personal prayer language" also called tongues.

What do you think?

OK, since I kind of want to let this be the last entry on this subject let me add this verse to the overall conversation and get your response.

"...my brothers, be eager to prophesy, and do not forbid speaking in tongues. But everything should be done in a fitting and orderly way." (1 Corinthians 14:39)

That word "eager".... hmmmm.
