Have you ever looked up at the sky and felt astonished? We all have. Whether it is admiring a gorgeous sunrise or sunset, seeing the innumerable stars on a clear evening, or just feeling soo small amidst the vastness of the heavens, the sky is always an echo to us. As we move into the second day of creation, we discover that the sky is more than beautiful. It was intentionally designed by God to reveal His order, His authority, and His glory.
