Our assumptions about reality are as wineskins are to wine: they are about, or contain, it. Jesus is the wine. But a new wine that doesn't taste as good. He is reality. But a raw one. And to say something about how wineskins contain wine is to say something about how our assumptions contain Jesus. Jesus says if a man tries to put new wine in old wine skins, it won’t work. He has to change his assumptions to take in and hold a thing like Jesus. So all his assumptions—the skin around his reality—must be brand new, as new as the new wine, so they can be supple enough to grow as Jesus grows him and in him. However, if he tries to put new wine in an old wine skin, then the new wine will burst the old wineskin and he will lose everything: both his new God and his old one.
