It amazes me how many "Christians" do not believe in the Bible literally because it contains miracles. It is both unbelieving and idolatrous. Unbelieving because it does not believe what the Bible says. Idolatrous because it imposes a naturalistic standard onto Scripture. If God is who He says He is, then He is not confined by His own created rules. He transcends them all. Whatever makes sense, what is natural, He is Lord over. Whatever is chaotic, unnatural, He is still Lord over.
That's a different topic than whether Apostolic sign gifts are still normative in the Church today. I do not believe they are, but that does not mean I do not believe in miracles.
