“Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.”
Probably the first thing that comes to your mind when yeast is mentioned is its use in making bread. Even three and a half thousand years ago, when Israel left Egypt, yeast was in common use.
Physicists at AT&T Bell Laboratories have learned that yeast has yet another amazing ability. For years, scientists have tried to make semi-conducting crystals for modern electronics that are as small as individual molecules. But scientists had difficulty making such crystals consistently small enough. Now they know that yeast can do it. When fed cadmium sulfide, yeasts try to detoxify the metal and in the process, produce precisely those tiny electronic crystals scientists have been looking for. Someday you may bake bread made with yeast in a microwave oven that is controlled by a computer containing tiny electronic parts also made by yeast!
Because the Bible is a real-life book that tells about a real-life God – the true God – we should not be surprised to learn that the Creator is interested in man’s real-life everyday activities. We can also explore what He has created, always expecting to learn some new thing that He has placed in His creation to help us. But the most important thing we can learn is how excellent and true is the real life-saving Word of our Creator for us today!
Dear Lord Jesus Christ, I thank You that I can clearly see that You are interested in all aspects of my life. Help me to remember Your all-encompassing love and care as I face life and as I help others face life with You. Amen.
