NOTE: The following section is provided by Pastor Mark Strohkorb, a personal and good friend of mine and a brother in Christ. I was not satisfied with my commentary on this portion and the Lord graciously directed Mark to my blog and compelled him to send me an explanation for the parable of the leaven that I think is much more edifying and, more importantly, scripturally correct than the traditional interpretation.
Amen Mark, Amen!!! And thank you!
"My own sense is that the use of leaven, is in this instance does not represent sin. I believe it represents the way we take the Word and hide it in our hearts (three measures of meal = man as three part being; body, spirit, soul). Woman represents the church. We take the Word into our hearts through the agency of the church (Rom.10:14). And just as leaven causes the bread to rise, doing its work unseen, inside, in the darkness --- so the Word mysteriously goes to work from the inside out; soul, spirit, and body, giving 'life' to the bread which becomes food for others once it matures (i.e., rises). The 'rising' in this case is not the puffing up of pride, but the growth (often hidden in one's life) until it becomes apparent that God is 'rewarding' openly the secret work He has been accomplishing by His Spirit (Mt.6:4,6,18).
"Though leaven was a type of sin throughout the Old Testament, remember there was leaven in the wave offering at Pentecost. This is a beautiful type of the Church. There were two loaves used (vs. one at Passover). Two here simply represents plurality. Whereas there is no leaven at the Passover meal and only one loaf (Hear O Israel, the Lord Thy God, the Lord is One), at Pentecost (representing the birth of the Church) both loaves are baked WITH leaven. Obviously this demonstrates that there is NO sin in our Lord Jesus Christ, while there IS in His church. Note, however that the offering itself still pertained to Christ.
"It doesn't make a lot of sense to me to declare that the Kingdom of Heaven is 'like unto leaven,' if leaven is sin. So the Kingdom of heaven (in this model) is like sin which the woman (the church) intentionally fills the church with in order to spread that sin thoroughly throughout. Just doesn't work for me. I believe the sin model works perfectly for the previous parable. A grain of mustard seed (smallest of all seeds; e.g., "for who hath despised the day of small things..." -- Zech 4:10) becomes so great (large; accommodating) that even the birds (evil spirits, cf., Mt 13:4,19) nest in its branches. I can see evil nesting inadvertently among the righteous. But I can't see evil as the intent of the Church, sown throughout."
NOTE: The following is my original post:
Today's reading contains several notable subjects. First, I think it remarkable that after Jesus blessed and commissioned His disciples in chapter 10, the first verse of chapter 11 states that he immediately went and did what He instructed them to do. Matthew 11:1 states, "When Jesus had finished giving these instructions to his twelve disciples, he went out to teach and preach in towns throughout the region." Once again, the Lord not only teaches but demonstrates exactly what He wants done.
In chapter 13, the third major discourse in Matthew is presented. To review, the first discourse was to the people who attended synagogue and the second was to His disciples. The third sermon is to those who are following him. This discourse also begins Jesus' parabolic ministry. This type of teaching required the listener to have a spiritual ear and understanding. He explains to His disciples why he teaches in parables, "You are permitted to understand the secrets of the Kingdom of Heaven, but others are not. To those who listen to my teaching, more understanding will be given, and they will have an abundance of knowledge. But for those who are not listening, even what little understanding they have will be taken away from them. That is why I use these parables."
He presents seven "Kingdom of Heaven" parables. The first three are related to grain/seed: the sower; the wheat and tares (weeds); the mustard seed. The fourth deals with leaven (yeast) as an evil influence. The fifth and sixth deal with hidden treasure and treasure (pearl) to be gained at any price. The seventh is the net that brings in all types of fish.
All of these have a meaning. In the first parable where the seed lands when sown determines whether is thrives or dies. We need to provide the correct environment of the Word of God to grow in us. The second is indicative of the evil influences (the tares) the devil places around us. From this we learn to rest in Christ and not be influenced by evil. The third parable - the mustard seed - is symbolic of the speed with which the Gospel of Jesus Christ grew and took root. The fourth parable - the leaven (yeast) parallels the Old testament references to leaven as evil and pervasive.
The fifth parable - the hidden treasure - is representative of Israel, who Christ found and paid everything for. The sixth parable - the pearl of great price - represents the Church. The pearl is a symbol of unity and comes at the price of God's Son, Jesus. The final Kingdom parable is the parable of the net. This represent the preaching of the Gospel which brings in all types, but through time, those who do not believe are cast out.
At the end of chapter 13, there is a final parable. This is not a Kingdom parable but speaks about those who convert from the Law to Grace. They are then able to go to their storehouse for gems of truth, i.e. the Word of God.
May God bless you and bless the reading of His Word.
