"unbelief" does not stop God from causing us be born again, the Holy Spirit from quickening the dead spirit in us, the sign gifts were assigned to the apostles, they had no idea of asking for them or even what to ask for!
Jesus healed an unbeliever, yet sent away believers who asked for healing
The Godhead all speak all languages........a prayer language is not biblical as it would have to be something given to everyone as all Christians pray.....sometimes with hearts so broken we groan our need for grace.
The very fact that these sign gifts are only manifested in charismatic circles shows something is not right.
Charismatic sign gifts have also been manifested in cults, like the mormonism, catholocism and odd sects like the Shakers and others
A movement that began as a "renewing" in the 1800's, one has to ask, where were they before?
doesn't your head hurt from all the spin you are putting on what scripture so plainly state?
the Bible clearly identifies praying in the spirit. the following is both instructional to the church at Corinth but also makes plain different ways tongues are used
1Earnestly pursue love and eagerly desire spiritual gifts, especially the gift of prophecy.
2For he who speaks in a tongue does not speak to men, but to God. Indeed, no one understands him; he utters mysteries in the Spirit.
3But he who prophesies speaks to men for their edification, encouragement, and comfort.
4The one who speaks in a tongue edifies himself, but the one who prophesies edifies the church.
5I wish that all of you could speak in tongues, but I would rather have you prophesy. He who prophesies is greater than one who speaks in tongues, unless he interprets, so that the church may be edified.
6Now, brothers, if I come to you speaking in tongues, how will I benefit you, unless I bring you some revelation or knowledge or prophecy or teaching?
7Even in the case of lifeless instruments, such as the flute or harp, how will anyone recognize the tune they are playing unless the notes are distinct?
8Again, if the trumpet sounds a muffled call, who will prepare for battle?
9So it is with you. Unless you speak intelligible words with your tongue, how will anyone know what you are saying? You will just be speaking into the air.
10Assuredly, there are many different languages in the world, yet none of them is without meaning.
11If, then, I do not know the meaning of someone’s language, I am a foreigner to the speaker, and he is a foreigner to me.
12It is the same with you. Since you are eager to have spiritual gifts, strive to excel in gifts that build up the church.
13Therefore, the one who speaks in a tongue should pray that he may interpret.
14For if I pray in a tongue, my spirit prays, but my mind is unfruitful.
15What then shall I do? I will pray with my spirit, but I will also pray with my mind. I will sing with my spirit, but I will also sing with my mind. 16Otherwise, if you speak a blessing in spirit, how can someone who is uninstructed say “Amen” to your thanksgiving, since he does not know what you are saying?
17You may be giving thanks well enough, but the other one is not edified.
18I thank God that I speak in tongues more than all of you.
19But in the church, I would rather speak five coherent words to instruct others than ten thousand words in a tongue. I Corinthians 14
