Clearly seeing the invisible.
Romans 1:20 says:
“For since the creation of the world His invisible attributes, His eternal power and divine nature have been clearly seen, being understood through what has been made, so that they [men everywhere] are without excuse.”
This is an interesting paradox that the invisible is seen. Renee Descartes describes a similar idea of the invisible being seen in the creation using the right triangle. In any right triangle its invisible “soul” is: a2 + b2 = c2. It is the invisible truth that pre-exists the drawing of any right triangle. It was only as Pythagoras studied the nature of the right triangle that the invisible truth was seen.
So it is with God, as we study what He has placed in front of us. We can “clearly see” at least two of His attributes from creation: “His eternal power” (He is outside of time) and “divine nature” (He is God and not man). These two features are what leave men without excuse throughout history. Men of all times and places can know they are not alone. And they can ask, what might a God like that be like…?
