Challenge: The Bible says God doesn't change, so we should expect Him to [give revelation, semi-revelation, revelatory/attesting sign-gifts, do exactly as He did in the days of ____, etc.].
Response: Yeah.... Oh and say, can I have a bite of that ham sandwich? Cool shirt, by the way. And hey... where's your lamb? Well, see you in church Sunday, when you draw near to God to bring your spiritual offerings directly to Him through Christ, wherever you decide to worship.
