It is definitely relevant. You keep claiming that tongues is a sign to unbelievers. I'm telling you that when Cornelius spoke in tongues, there were no unbelievers present. Therefore, your view regarding the sign of tongues is not valid.
I have explained this several times. I suggest that you read Acts 10 so that you understand the context.
You offered but offer no explanation.
You say it is relevant but give me no idea as to what? I understand the context perhaps you don't have a proper spiritual understanding?
Show how you idea is relevant . . . still waiting for the first time...
