There is something awe-inspiring in the appearance of a rainbow after a storm and it is arguably one of the most photographed and well-known meteorological phenomena on the planet. But beyond the natural beauty, there are spiritual aspects of the rainbow that have major significance. Anyone who believes that God tolerates sin presumes upon His mercy and grace and ignores His holiness and righteousness. The rainbow is a beautiful, yet powerful, reminder that God is both merciful and holy. He keeps His promises. And every rainbow that appears in the sky is our constant reminder.
