From the movie, "Contact", as spoken by two of the characters:
"It seems like an awful waste of space."
No it it doesn't!
The vastness of the universe is an incredible visual aid!
The God of the Bible is giving us a glimpse of who we are and who He is.
How awesome is His power. How wonderful is His mercy and grace.
"When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained; What is man, that thou art mindful of him? and the son of man, that thou visitest him? Psalm 8:3-4
"The heavens declare the glory of God; and the firmament sheweth his handywork." Psalm 19:1
"Who hath measured the waters in the hollow of his hand, and meted out heaven with the span, and comprehended the dust of the earth in a measure, and weighed the mountains in scales, and the hills in a balance?" Isaiah 40:12
The vastness of space is a very effective visual aid to those our Lord Jesus created in His image to show us objective evidence of His existence and to exhort us to be humble before Him.
An Incredible Visual Aid for a Very Important Event
And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be. And he believed in the Lord; and he counted it to him for righteousness.
