Psalm 19:5-6 contains several interesting scientific facts. In speaking of the Sun, the psalmist suggested that “his going forth is from the end of the heaven, and his circuit unto the ends of it; and there is nothing hid from the heat thereof.” For years, Bible critics scoffed at Bible believers, stating that this verse taught the false concept of geocentricity (i.e., the Sun revolves around the Earth). Then it was discovered that the Sun, not the Earth, was the center of our solar system. People subsequently felt that the Sun was stationary, with the Earth revolving around it. Only fairly recently has it been discovered that rather than being fixed in space, the Sun actually is in an orbit of its own. In fact, it is estimated to be moving through space at the rate of 600,000 miles per hour, in an orbit so large it would take approximately 220,000,000 years to complete just one orbit. How did the psalmist portray such accurate statements—when people of this day, and for centuries afterward, taught that just the opposite was true? And, by the way, there is another gem packed away in these two verses. The psalmist hinted at the fact that the Sun is the source of energy for the Earth (“and there is nothing hid from the heat thereof”). An amazing statement, is it not, considering when it was written, and by whom?
