“I tell you, my friends, do not fear those who kill the body, and after that have nothing more that they can do. 5 But I will warn you whom to fear: fear him who, after he has killed, has authority to cast into hell. Yes, I tell you, fear him! 6 Are not five sparrows sold for two pennies? And not one of them is forgotten before God. 7 Why, even the hairs of your head are all numbered. Fear not; you are of more value than many sparrows. -Luke 12:4-7
When I was a boy and one of our friends hurt themselves, we had a trick to help them with the pain, “Hey, do you want me get the pain in your finger to go away?” And then we would punch them in the arm so that their arm would hurt more than their finger, thus making them forget the pain in their finger.
Humans naturally pay attention to whatever is causing, or has the ability to cause, the most pain. Jesus knows this, so he reminds us all that the one who can cause us the most pain is actually God himself.
