Again he asked, “What shall I compare the kingdom of God to? It is like yeast that a woman took and mixed into a large amount of flour until it worked all through the dough.” Luke 13:20-21
This is one of the few times in Scripture where yeast is not compared to sin. Most often it is used to speak of the way sin changes the state of a person’s heart. But in this case, that change is a positive one. The Gospel (the kingdom of God) actually alters the very nature of human development.
I came to know Christ in college. To many around me, the changes that took place in my life were probably considered changes that came with maturity and human development, but I knew different. There was a significant difference between the “BC” person and who I became.
Though my life as sheltered and stable, I grew up with no real sense of personal value. Before I came to Christ, I had no understanding of why I existed. I was scared to try new things because I feared ridicule or that I would fail and people would think poorly of me. I’m sure it was not intentionally communicated, but I believed my personal worth was a function of some unique contribution that I knew was not in me. Had I embraced an Eastern mystical religion in those days, it would have fit my don’t-rock-the-boat demeanor. I wasn’t passionate about anything so that I would avoid being criticized.
But Christ changed that. His presence in my life began to permeate everything I was and did. That “small” decision to trust Him with my life suddenly impacted the whole of my life, just like the yeast did to the dough in Jesus’ illustration. I recognized the Bible as the source of Truth; I saw Jesus as the Ruler over the universe; I may not have had clear vocational direction, but I knew it was somehow connected to my relationship with Him. All the pieces of my life that had previously seemed so fragmented, now were brought into order by His presence, like a magnet does to iron filings.
But it makes me wonder about some of the people near me. Has their internal orientation changed because of their decision to trust Christ? (Has the Gospel yeast permeated their lives?) Rather, have they viewed Christianity as “fire insurance,” simply to keep them from hell? When small children (even my own) trust Christ, does the Gospel yeast so alter their lives that they will be true to it in the turbulent adolescent years and beyond? Certainly, I can never peer into the hearts of these near me, but He does expect me to inspect the “fruit” or see if “the dough has risen.”
