Messier 94 galaxy Now that my daughter is at university, I've been able to vicariously enjoy tidbits from her classes. In her astronomy class, her professor said there are four fundamental forces in physics - strong nuclear, weak nuclear, electromagnetic, and gravity. Which one do scientists know the least about? The answer is gravity. I found this very interesting because gravity is so common that we take it for granted. Yet this force is still a mystery to the best brains in physics. But for those who believe in a Creator God, we may not be scientific geniuses, but we can acknowledge gravity as His handiwork. So for this thankful Thursday, I am thankful for the privilege of knowing God as Redeemer and Creator. I am thankful that I can see and experience the work of His hands, and this leads me to worship Him.
