One of the fun things about having children is being a witness to their imagination. Gracie enjoys drawing pictures and making up stories to go along with her artwork. When we are playing together, she will sometimes tell me the story she's just drawn and then wants me to act it out with her. She calls it her "play" and she directs me as to how I'm supposed to act in her imaginary production because she knows how she wants her "play" to end.
According to Hebrews 12:2, Jesus is the "author and perfecter of our faith" because he came to this world in human form so we could learn from Him, follow His lead in obeying God. After the writer tells us to run this life's race with perseverance and to throw off everything that hinders us in living the Christ-centered life, the writer tells us to follow the leader; the One who has already gone before us to show us the way. The Bible tells us to "fix our eyes on Jesus" (another translation says "looking to Jesus" in Hebrews 12). When you are in the zone running the race of life and you are focused, you aren't looking at everything else going on around you. You aren't looking at things that can trip you up.
So in this race we run as Christians, Jesus could be thought of as the author because He wrote the script; Jesus can also be thought of as the director because He shows us how to play our assigned role so that our actions conform to the author's original design. Are you playing the role that God designed for you to play for Him?
