In the Beginning - Lesson 4 - Creation: Day Four - Sun, Moon, and Stars - Genesis 1:14-19. On day 4 of creation God created the greater and lesser lights for signs, seasons, days, and years. In the discussion of light and time, we discuss time dilation as God stretches the heavens out "like a curtain" and look toward our hope as one day He will roll it all up like a scroll!
