That is all? That is the big help "tongues" has been for you? You merely reiterated what is given in Scripture.He showed me once that we are to believe ONLY, not believe mixed with doubts. One example He showed me was that if a person, in order to say, save a drowning child, runs out on top of the water ( in the same way Jesus had walked on it ), while that persons faith is solid, so is the 'substance' that the person is 'walking/running on', but doubts are like punching little holes in the substance and once enough holes are there, they sink.....Heb 11:1......."NOW faith is the substance of the things hoped ( eagerly expected ) for, the evidence of things not yet seen." In my experience something described as 'substance' and 'evidence' , is not some airy fairy thing, but something REAL, and it was obviously real enough for Jesus to walk on ( and Peter too, till he doubted/feared ), when He walked on the water.
He also explained to me at the same time that :" Doubt is the beginning of fear." We cannot stop the enemy from bringing doubts into our minds, but we can and should reject them instantly and replace the thought of doubt with one of faith..... I am not suggesting that I am as yet perfect in this, or in any other thing to do with our life with/in Him, but I sure do love the way He can explain a thing to me, so that I can understand it, not being a learned person .... Be blessed always :)
BTW, whenever tongues are narrated in Scripture, they are never for a discrete and personally directed purpose. When tongues in Scripture are enacted, they are always part of a momentous event seen and experienced by all those present.
