Uncovering Circadian Clockworks

Every day everyone gets tired, but have you have ever stopped to wonder why? Or rather, how exactly your body knows its time to be tired?

Engine for Good

A sermon at church today focused on better understanding the power of godliness. While listening, I found myself asking questions, including: Where does power come from? How is it focused, used for good? When is it dangerous and how is it safeguarded? How is it developed or stored? What power does God want for us?
