A friend shared a great video that has to do with space and how big our God is. Although I am not familiar with the speaker I found nothing in the video to be inaccurate. I am not endorsing his other videos because this is the only I have viewed. It take approximately 40 to view in it's entirety. It is broken up into parts if you wish to view it over one or two a days.
The man's name is Louie Giglio with " If the earth were the size of a golf ball" or How big our God is. The link is below -
This is a great way to expand our knowledge of God without hitting the books so to speak. Truly all creation and subjects point back to Him.
To Him be all Glory,
