You have supported nothing. You have made unsubstantiated assertions. Would you care to explain the simple fact that leaven was used in the ceremonies of God at His command, in spite of your assertion that leaven is always a negative (whatever that means). How can God's worship be defined with a negative? And, again, where is the feast of unleavened bread does it make the statement, as you claim, that leaven is a negative?
Are you done with your diversion? Can we get back to the subject at hand which was the positive growth of the kingdom ala Matt. 13:31-33?
