"The Kingdom if God is like yeast which a woman took to knead into three measures of flour until a whole mass of dough began to rise."
Jesus liked to compare His Kingdom to small things, yeast, and seeds. Apparently there is not much fanfare or big signs point to His Kingdom. Yeast and seeds, especially the tiny mustard seed, are so small and insignificant. It reminds me of Mother Teresa who often compared herself to a little pencil. "I'm just a little pencil in the hand of a writing God, who is sending a love letter to the world." "I am a little pencil in God's hands. He does the thinking. He does the writing. He does everything and sometimes it is really hard because it is a broken pencil and He has to sharpen it a little more."
Jesus started with a little band of insignificant men and women like us. They weren't very intelligent. They didn't have Master's degrees from important schools. They weren't eloquent speakers at the start. They weren't even very brave. But just like a tiny seed which grows in the right soil, and yeast which makes dough rise, we too can contribute our gifts and talents, no matter how little, for God to use in the growth of His Kingdom. How wonderful if God would say to me, at the end of my life here on earth, that I was good seed, a usable pencil, living yeast!
