Most commentators see this parable as a positive message of the growth of the church. However, deeper study shows that they have it exactly backward!
Scripture uses leaven as a symbol of corruption. The mystery deepens with the instruction of not one leavened loaf but two. Why two leavened loaves?
Jesus warned of three varieties of leaven that we must guard against, staying aware of the pitfalls that will pull us down and corrupt us.
The Kingdom of God or of Heaven has past, present, and future aspects. The Kingdom parables primarily provide instruction for the present aspect.
The tares and wheat must coexist until the harvest when the fruit will become clearly seen, at which time a separation and judgment will take place.
The Feast of Unleavened Bread signifies far more than the avoidance of leavening. Our focus needs to be on God's management of the process of deliverance.
The meal offering represents the fulfillment of the second great commandment, "You shall love your neighbor as yourself." Here is how to understand this offering.
The Feast of Unleavened Bread immediately follows the Passover. In it we see how hard it is to overcome and rid our lives of sin.
The meal offering represents the intense self-sacrifice required in service to man. Our service to man must be done for God's sake rather than man's appreciation.
