"...covet to prophesy, and forbid not to speak with tongues" I Cor 14
There's a diversity of tongues =
"And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments,
diversities of tongues." (II Cor 12:28) including the edification for the believer (II Cor 14:4) and the church such as the gift of tongues with interpretation (II Cor 14:5).
Tongues are a sign TO unbelievers OF believers. (I Cor 14:22 and
Mark 16:17).
With the groups that received tongues in Scripture, it states
"all" that were there received (
Acts 4:31; 10:44-46; 19:2-6). With tongues, they magnified God (Acts 10:42).
"They were all filled and equipped with the Holy Spirit and were inspired to speak in
tongues—empowered by the Spirit to speak in languages they had never learned!," Acts 2 TPT
