Address what I said and the scriptures I gave instead of followstep and you giving me your personal opinions.
Speaking in tongues was a gift given, a sign, given (Isaiah 28:11) during the laying of the foundation of the Church (Hebrews 2:4). It was a sign to the Jews (Acts 2:6). Speaking in tongues has served God's purpose, God has given the sign (1Cor 14:21), and God has laid the foundation (Eph 2:20). Speaking in tongues by the Gentiles showed the Jews that God granted even the Gentiles repentance unto life (Acts 11:18). Tongue speakers spoke mysteries (1 Cor 14:2); consequently, the mystery of the gospel has been given (Eph 6:19). Speaking in tongues is the language of angels (1 Cor 13:1), angels minister to humans (Hebrews 1:14). Humans are to understand speaking in tongues in earthly languages (Acts 2:6, 11). Speaking in tongues would be “stilled” (1 Cor 13:8).
