NO GIFT can be wielded of our own accord. Only as the Spirit gives utterance.
Remember some of the OT prophets didn't want to be one?
God calls whom He will. It's not our choice.
Years earlier I spoke messages in tongues & gave interpretations. I would try to fight it because either I was unsure or didn't want to make any fleshly mistakes. But it's just like Jeremiah said when he wanted to stop. It's like a fire shut up in your bones.
Jer. 20:9 But if I say, “I will not remember Him Nor speak anymore in His name,” Then in my heart it becomes like a burning fire Shut up in my bones; And I am tired of holding it in, And I cannot endure it.
When it truly happens, I found I can't hold back.
