Isaiah 8:19 And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? for the living to the dead? Isaiah 8:19 is the only Biblical evidence that defines supernatural tongue as vain & profane babbling nonsense where it cannot be interpreted. Passage from Dr. John R. Rice's book, The Charismatic Movement in linking to Isaiah 8:19 above. So there is evidence that there is a supernatural tongue had been in world's religions today like Islam. There is also evidence that in some idolatrous practices, they had interpreters for those tongues, but I believe they were faking the interpretation since it was never a language of men. Paul touched on this before getting into the gifts of the Spirit although not really addressing that supernatural tongue. 1 Corinthians 12:1 Now concerning spiritual gifts, brethren, I would not have you ignorant. 2 Ye know that ye were Gentiles, carried away unto these dumb idols, even as ye were led. So we know that there was a supernatural tongue in the world before Pentecost that was just vain & profane babbling nonsense, and that it existed back in Paul's days and still does today. Now since it had been prophesied that some shall depart from faith in giving heed to seducing spirits & doctrines of devils; 1 Timothy 4:1-2 and this was why John warned believers not to believe every spirit but test them: ( 1 John 4:1-3 & 2 Corinthians 13:5 ) when any spirit that comes over a believer apart from salvation is the spirit of the antichrist; ( 1 John 4:4 ) because he did reference the supernatural tongue in the world as done by the spirit of error afterwards 1 John 4:5-6 ; then shouldn't believers be more discerning about the kind of tongues they are using today, especially when they assume that because it comes with no interpretation, that it must be a prayer language of the Holy Spirit or for some other private use rather than being of other men's lips to speak unto the people ( 1 Corinthians 14:21 )? If most tongue speakers take note as to when and how saved believers got that kind of tongues for "private use" running contrary to 1 Corinthians 12:7 since the purpose was to profit the body withal and not individually, it usually comes with a testimony of receiving the Holy Spirit apart from salvation. Such a testimony ignores the warning of 2 Corinthians 11:3-4 as their testimony lead others to heed this as another calling to seek to receive the Holy Spirit apart from salvation while seeking it by a sign of tongues which opposes 1 Corinthians 12:22 since tongues were never to serve as a sign or proof towards the believers but to the unbelievers. Indeed, 1 Corinthians 12:13 has Paul testifying to only one drink of the One Spirit by which we were ALL baptized by. 1 Corinthians 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit. Most tongue speakers today refer to another drink and another calling by which they had received that kind of tongue. Some believers will try to make it or even faking it as the real God's gift of tongues by guessing at what that tongue is saying and wing the interpretation by the "feel" of it. That is not how to interpret God's gift of tongues. No way. That is too much what the fake interpreters were doing with that vain tongue in their idol worship in Paul's days. I believe the real God's gift of tongues is of other men's lips to speak unto the people as it is manifested to profit the body withal, it will come with interpretation in the assembly. Prophesy is the gift to seek after; not tongues; and Paul did not tell them to seek the gift of prophesy by seeking to receive the Holy Spirit apart from salvation either. I know that tongue speakers will go tooth and nail taking verses out of context in 1 Corinthians 14th chapter as if to prove Paul was actually endorsing tongues for private use when that same tongue talked about in that chapter has to come with interpretation for the tongue speaker to understand in order for that tongue to be fruitful to the tongue speaker. That means Paul was comparing tongues by itself against prophesy to show why prophesy is the gift to seek, because tongues is not a stand alone gift for His tongue will come with interpretation to profit the body withal. Now I am asking tongue speakers to address scripture that opposes tongues for private use, because how can Paul keep out those idol worshipers of Corinth from the assembly from using their vain tongue? How can any born again believer convince the assembly at Corinth that they had repented of their idols and that kind of supernatural tongue if God "mimics" that same kind of tongue? How can tongue speaker apply His words below when tongues for private use mimics the tongue that is in the world? 1 Thessalonians 5:21 Prove all things; hold fast that which is good. 22 Abstain from all appearance of evil. Especially when that tongue gained is identified by seeking to receiving the Holy Spirit apart from salvation which is a departure from the faith and the traditions taught of us? 2 Thessalonians 2:13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: 14 Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ. 15 Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle. How can modern tongue speakers today ease the concerns of believers that they are not the ones prophesied as falling away from the faith in giving heed to seducing spirits and doctrines of devils in 1 Timothy 4:1-2 ? I believe that christian tongue speakers are still saved but are in iniquity for how & when they got that tongue, and my concern is legit in why they should shun that vain & profane babbling, pray normally, and no longer seek to receive the Holy Spirit or another infilling apart from salvation, because it goes against the traditions taught of us.
