19:61) about the sun--"his circuit is from the ends of the heavens."] What would happen if the rotation rate of the earth around the sun were halved, or doubled? If it were halved, the seasons would be doubled in length, which over most of the earth would cause such harsh summer heat and winter cold that not enough food could be grown to feed the world's population. If it were doubled, no single season would be long enough to grow the amount of food necessary to feed the world's population. [Remember God's words to Moses: (a) "Let there be lights in the firmament of heaven to divide the day from the night: and let them be for `signs and for seasons', for days and for years" (Genesis 1:14, emp. added), and; (b) "While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease" (Genesis 8:22).] Then there is this matter: from where does our day come? It comes from the earth's rotation once approximately every 24 hours on its axis. From where do we get our month? It comes from the moon circling the earth once approximately every 28 days. From where does our year come? It takes the earth approximately 365.26 days to go around the sun. `But where do we get our week?' There is no purely natural explanation for the week. The explanation, instead, is found in Exodus 20:11 (cf., Exodus 31:17): "for in six days Jehovah made heaven and earth, the sea, and all that in them is, and rested on the seventh day...." The week is an entirely universal phenomenon. Yet there is no purely natural explanation for it. Little wonder Isaiah wrote (40:26): "Lift up your eyes on high, and behold who hath created these things, that bringeth out their host by number; he calleth them all by names by the greatness of his might, for that he is strong in power; not one faileth." The fundamental law of science, we repeat, is the Law of Causality which states that every effect must have an adequate cause. There i...
