Then we should never privately pray or worship either since that only edifies the self. Or, like I've already noted, the body can still be edified by private intercessory prayer, and the same is true of praying in the Spirit---we can intercede on behalf of others.Then you can never separate that pagan supernatural tongue which is in the world form the real God's gift of tongues.
1 Corinthians 12:4-11 testifies that the gifts are to profit the body of Christ, the assembly.
1 Corinthians 12:4 Now there are diversities of gifts, but the same Spirit. 5 And there are differences of administrations, but the same Lord. 6 And there are diversities of operations, but it is the same God which worketh all in all. 7 But the manifestation of the Spirit is given to every man to profit withal. 8 For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit; 9 To another faith by the same Spirit; to another the gifts of healing by the same Spirit; 10 To another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues: 11 But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
Paul specified that these gifts are not sought by seeking a baptism with the Holy Ghost when they are already born again of the Spirit and thus a member of the body of Christ. Verse 13 below is the testimony we are all suppose to share and that includes no more filling of the Spirit for that would mean one member had another drink of the One Spirit to be filled again..
12 For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ. 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. 14 For the body is not one member, but many.
AND Paul says these gifts were never meant for any member of the body for private use.
18 But now hath God set the members every one of them in the body, as it hath pleased him. 19 And if they were all one member, where were the body? 20 But now are they many members, yet but one body. 21 And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
So what does that mean for your verses in 1 Corinthians 14:2 & 4 ? You are reading tongues for private use into the verses and therefore not rightly dividing the word of truth.
The greater concern is you are calling Scripture heresy. 1 Corinthians 14.2 says it plain as day:
2 For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit.
I don't know why you seek to deny the clear teaching of God
