"Still, it is also characteristic of a true disciple of Jesus that he is not afraid of the world. Matthew 10:28: "And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell." There's no reason to be afraid, because, as a follower of Jesus, you know you will happily trade whatever perils you face in this world for the riches of your reward in the eternal world to come. Disciples joyfully "speak in the light" and "preach on the housetops" (v. 27), untroubled by any rebuke or threat. Furthermore, there's no reason to fear what happens here, because not even a sparrow falls (actually the word means "hops") to the ground outside of God's will. "But the very hairs of your head are all numbered. Do not fear therefore; you are of more value than many sparrows" (w. 30-31)."
