I Felt I Should Drop in and Explain Why I Left

I would say that satan may destroy en masse or in individual [Judas, King Saul, etc], and therefore, the mere fact that it is "private" is not safety. Thousands, millions, have "private" sins, practices, etc, which they do not make public. These private sins, practices, may not destroy en masse, but they do still work the destruction of the individual. Satan looks to pick off the individual from the flock, even as a lion.

Also, Jesus, said nothing in secret:

John 18:20 KJB - Jesus answered him, I spake openly to the world; I ever taught in the synagogue, and in the temple, whither the Jews always resort; and in secret have I said nothing.​

 

There are no personal prayer tongues, so what langue is the Lord giveing you to give to others? is it in an evagelism outreach, or what?

There is no such thing in Bible as personal prayer tongues, so what real language has he given to you, and how have you been using it for Him?

 

When you say Apostles ansd prophets, do they give additional revelations from God to their church? Do they do miracles/healings as Apostles did? Do they speak and teach infallible?

 

There have been instances upon earth where languages have been outright created in phantasy [sci-fi, science falsely so called], such as:

6 Fictional Languages You Can Really Learn

Elvin and Dwarvish [etc] in Lord of the Rings, by Roman Catholic Tolkien
Klingon, Vulcan, etc in Star Trek, by kabbalist pornographist Leonard Nemoy
Lapine in Watership Down, etc
Gnomish in Dragon Lance, etc
​

Worlds I used to live and breath in, in the days of my madness, and was even 'creating' [inspired of the devil] a language, in the sci-fi/phantasy realm which was ever changing, called [well I won't say, let it remain buried], including an entire world structure [I can only describe it like how others received such images, and visions for their worlds, whole things were coming to me then, it would have been more deadly than what I have mentioned above, there were plans to go from print to an entire video, movies series and more].

However, even in these sci-fictional/phantasy languages, they are based in real language structure, syntax, verbage, endings, nouns, verbs, predicates, subjects, etc.

 

It is written:

Psalms 77:13 KJB - Thy way, O God, is in the sanctuary: who is so great a God as our God?​

Therefore, your doctrine, teaching, theology, and practices must be found to be based in God's Sanctuary, or it is counterfeit to it, for we are not ignorant of satan's devices, for all he does is, is to twist that which is in the sanctuary itself, in everything.

Jesus said:

John 14:6 KJB - Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

John 6:35 KJB - And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.

John 6:51 KJB - I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
​

In the sanctuary, there was "bread" on the table of Shewbread, on the sides of the north, which represented Father and Son, upon their throne in the Holy Place, even the word of God. It was always in proper order, in two stacks of 6, every piece in their proper place. God is also the Alpha and Omega. Thus, the same way with words, having proper beginning and ending, all connected within, one to the other. Furthermore, in the Most Holy place, we see the Ark of God [the Throne of God in the Most Holy Place], within which, was the Ten Commandments, the very "word" of God, again, in proper order, proper sphere, to God first, and to mankind second, with clear delineations. Each clearly discernible, nothing confusing, always shedding light. The 7 branch candlestick, being light was to be properly filled, and to be filled with a specific item, not what we choose of ourselves, or what we feel like filling it with. Same with the altar of incense, for prayer, it was to be properly cared for, and the incense itself, was to be properly made, in specific mixture and ratio, and nothing else was to be used, in any other mixture. Even the sacrifices in the courtyard reveal something to us in matters of speech [only that which is acceptable to God may be given, and all else is to be burned up, cut away, therefore let our speech be truth, unmingled with error, etc]. Even the ordered and structured Heavens themselves tell us something of speech, each with definite purpose, each having their proper and distinctly defined name/character [Psalms 19:2 KJB - Day unto day uttereth speech, and night unto night sheweth knowledge. & Psalms 147:4 KJB - He telleth the number of the stars; he calleth them all by their names.]. The same with language, in song, prayer, speech:

Colossians 4:6 KJB - Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.​

 

Does your group claim to have Apostles/prophets in their midst?

 

Do the prophets give additional revelations from God, are they infallible? Do they predict the future?

 

How can you translate gibberish?

It is not tongues/languages it is gibberish. There is not a plural of gibberish.

As someone already said there were those in the past there were those who spoke in real recognised languages. In France in the 17th century there were those known as the French Prophets. There were those mainly children who prophesied in good French even though "in their natural state, they would not know it knowing only their regional language" probably the Ocitan Language. (Languedoc, the language of OC Langue in French is Language and also tongue)
One of the child prophets is said to have prophesied in good French even though it had not learned to speak, or "go by itself". Warnings, by Elias Marion one of the French Prophets, English edition 1705.

Extracts from the above can be found in Modern Claims to the Extraordinary gifts of the Spirit, by Rev Wm Goode 1833. Republished in recent years under the title of Charismatic Confusion.

A Baptist Pastor I know, said he had been in the Pentecostal Charismatic movement for fifteen years, and had attended hundreds of healing meetings and had never seen any healings .

 

2Ti 4:3 For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions,
2Ti 4:4 and will turn away from listening to the truth and wander off into myths.

 

the scriptures state that one must be 100 % accurate though!

 

Then if you will do a brother a favour? Go to the Bible [preferrably KJB, use a KJ Concordance if you have to], and pray before beginning, asking God for light, truth and the Holy Spirit to lead you to those places therein where it speaks about speech, language, tongues, tongue, mouth, lips, chords, instruments [your voice is a stringed instrument, and a wind instrument], teeth, written, write, epistle, prayer, etc, and study every text on these things, until you have absolute conclusion from God's own word, believing that which is written, from Alpha [Genesis] to Omega [Revelation], which was given by holy men as they spake by the Holy Spirit. If you do this in true sincerity of humble heart, you cannot be led astray, but will be guided rightly. Will you do this brother?

 

I once picked up a book in a bookstore, entitled Charismatic Renewal. There were chapters on CR in various christian sects and even one on Charismatic renewal amongst Muslims.

Ecstatic "tongues" are not confined to so called christian sects but are also well known in Pagan religions, particularly Roman Catholics.
