I can see how you misunderstood what I said. So sorry for the confusion. Let me say it more clearly........
Speaking in tongues is necessary meaning that it has a purpose which is to edify; however, it is NOT a gift a believer must have to be edified. It has a purpose, therefore it is necessary.
Any gift God wants to give me, I want to receive because I love Him - the Giver of the gift.
It's God's gift. If I speak against it, I'm not speaking against the gift, I'm speaking against the Giver of the gift. I love God and would never want to speak against a gift of His.
Any gift He has given you, I am not going to say it is not necessary and doesn't exist anymore. I am going to rejoice with you because of the goodness of God.
I hope you understood what I have said.
