You don't know the half of it when it comes to today's tongues. From their roots in voodoo to their being learned from false teachers
Such tongue are associated with an apostate calling of seeking to receive the Holy Spirit again apart from salvation with evidence of tongues or by a sign of tongues for already saved believers to seek after.
when in Acts they were spontaneous and the speakers knew what they were saying.
Only when it is interpreted. They knew they were speaking some unknown language of men but until interpreted, they cannot understand it for that tongue to be fruitful to themselves.
1 Corinthians 14:12 Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church. 13 Wherefore let him that speaketh in an unknown tongue pray that he may interpret. 14 For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful.
Some have misapplied Paul's words for use of tongues in private use as if the Holy Spirit is praying out loud His own intercessions which is also false per John 16:13 but it is Paul's spirit that is praying that someone will interpret that tongue that is being manifested by the Holy Spirit because he wants to understand what is said.
Also, they only came through an Apostle's hands beyond the two outpourings.
Only came through an Apostle's hands beyond the two outpourings? Unless Paul said that or any of the other apostles, that is an assumption not confirmed by scripture, but can be reproved by scripture.
Hebrews 11:1.Now faith is the substance of things hoped for, the evidence of things not seen. 2 For by it the elders obtained a good report.
Galatians 3:14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith........26 For ye are all the children of God by faith in Christ Jesus.
How would the apostles or Paul move on from church planting if only an apostle can be the means for which the gift of tongue can come? Or was that what you had meant? The Holy Spirit with tongues? Then I would have to disagree since tongues are not to serve as a sign to believers that they are saved or that they have received the Holy Spirit at their salvation. Tongues are to serve as a sign or proof to unbelievers.
1 Corinthians 14:20 Brethren, be not children in understanding: howbeit in malice be ye children, but in understanding be men. 21 In the law it is written, With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord. 22 Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe.
Feel free to clarify but I did include reproof in case you meant the worse.
