Two different types of tongues in scripture...as in the below which I will post again.
If the "tongues" given for the assembly is speaking out with a subsequent gift called the interpretation of tongues is used to speak to men for consolation and for comfort and for edification of the hearers - because it is the same as simple prophesy....then wwhy does the devotional tongues in 1 Cor 14:2 say that we are speaking unto God and not unto men.
So, you see there are 2 types of tongues - one for the personal prayer time for the Lord and one for the assembly of believers to bless them.
One speaking in tongues is to the Lord - the other which is as the Spirit wills ( with an interpretation ) is speaking to men.
There is a manifestation of the Spirit for the assembly of believers called the gift of tongues which needs to be interpreted ( these occur as the Spirit wills - not us ) but that is not to be confused with the personal devotional tongues available to all believers ( this we can do as we will..see 1 Cor. 14:14-15 ) for praying to their Father and Lord as can be seen in 1 Cor 14:2
Then poor belivers in Christ who lived before 1906. And pleass tell me why people in heresy groups and pagans can speak in tounges too.
