“The kingdom of heaven..."Jesus is continuing with his parables regarding the nature of the spiritual realm.
The word "kingdom" is translated from the Greek word βασιλεία (basileia), which means, according to the lexicon, "royal power, kingship, dominion, rule; not to be confused with an actual kingdom but rather the right or authority to rule over a kingdom."
Jesus is not referring to a physical place here. He is referring to a consciousness. The consciousness relating to our relationship with the Supreme Being.
So we must ask, why would Jesus continually speak about the kingdom of God with parables? The answer lies in the fact that the subject matter - spiritual consciousness - is not easily understood by the physical mind. The mind maintains a collection of images, sounds and other sensual information taken from the physical world. The Supreme Being is therefore not able to be perceived by the physical senses.
Therefore it is difficult to understand spiritual consciousness - ones relationship with the Supreme Being - with the physical mind. Using parables allowed Jesus to compare aspects of the spiritual realm with certain parts of the physical world.
“... is like yeast that a woman took and mixed into a large amount of flour until it worked all through the dough.”Here Jesus compares the spiritual realm to the blending of yeast throughout a dough being made by a woman. Is he saying the spiritual realm is like bread? Certainly not. He is focusing on the action of yeast as it mixes into the dough. Yeast allows the dough to rise and expand in order to make bread. Without the yeast, there could be no bread. The dough would not have any activity - or life - to produce the dough's rise.
The “yeast” is the relationship of love that exists between God and each of His children. This is the essence of the spiritual realm, and the driver for the growth of our own spiritual life.
In the spiritual realm - spiritual consciousness - the spirit-person (each of us is a spirit-person, not these temporary physical bodies) has a unique loving service relationship with the Supreme Being.
This relationship is reciprocated by the Supreme Being. In the spiritual realm, in other words, there is a reciprocation of love between God and His children.
Jesus is comparing this to the mixing of dough and yeast because this relationship gives rise to pleasing the Supreme Being, which pleases the living being who loves the Supreme Being.
This is an escalating situation because as ones love increases, they increasingly please the Supreme Being and this gives increasing pleasure to the living being because they want to please God.
In our original position we were created by God to share love with Him. Just as it is with all relationships, love is executed through loving service.
In order to have real love and real loving service, however, we must have freedom. The Supreme Being gave each of us the freedom to choose to love Him or not. Those of us who chose not to love Him came here to the physical world, where we are able to hide from the Supreme Being and seek our self-centered objectives.
Even in this overtly self-centered physical realm, we can see that love is the still most important aspect of each of our lives. All living beings need love. Without God’s obvious presence (He is here, but our physical eyes were designed not to be able to see Him) we are each seeking love within the temporary forms of the physical world. We try to satisfy our need for our relationship with Him in our temporary families, spouses, friends, facebook accounts, fans or fellow organization members.
All of these efforts are futile, however. We are simply not satisfied by these temporary physical relationships. This is why we keep looking for real, unconditional love outside of the relationships we already have. Even those with large extended families find themselves looking around for that perfect unconditional loving relationship. This is because the unconditional loving relationship we are looking for is our original loving relationship with the Supreme Being.
This unconditional loving relationship is the yeast of our dough. The dough in Jesus' parable is God's creation: everything that exists. The yeast is the unconditional love that exists between God and His children. No living being can be happy without this unconditional love from the Supreme Being. Without our personal relationship with God, there is no happiness and no real life: just as there can be no real bread from flour without yeast.
