We say good-by to cheese for a period of time to open our hearts and minds and bodies to what the Lord wants to give us: new life. Eating cheese is like eating death in that we eat milk transformed into something new, exciting, robots for the whole of the body, mind and soul. But the Christian is asked to make a 40 day sacrifice of dairy products like cheese so that we can prepare ourselves for glory. God wants us to be a new creation in Him. And sin prevents us from this fact. Corporate sin and personal sin.
