Credible evidence, no one who believes in cessionism wants credible evidence. They believe there is such a thing. So as another poster said, each believes what they believe, why cause division?
You’re making an assumption based on feelings and not actuality. If I have certain evidence based in scripture and historical records to indicate God gave certain people specific gifts at a particular point in time and that has ended that for now, some will say that I don’t enough faith and that’s just not true. Saying what’s true for me and not for thee is a logical fallacy. God does not operate on what you or I believe to be truth.
