In Matthew 10:28-31 we’re commanded to not fear. The reasoning behind this command is that nothing in this (temporary) life can ever touch your (eternal) soul. So even if you are at risk of death, you don’t fear because the worse-case-scenario is death of your body, and it’s going to to die eventually anyway.
The passage further reassures us against fear by letting us know that God knows his children. He knows their name and their location and even the number of hairs on their heads.
Fear melts when there is someone who can remedy any situation. As a child, I never feared the dark when my father was with me.
Well child of God, your father is with you. So live without fear. Cast your cares upon him. Refuse to be paralyzed by fear and instead run your race with endurance.
“Don’t be afraid of those who want to kill your body; they cannot touch your soul. Fear only God, who can destroy both soul and body in hell. What is the price of two sparrows—one copper coin? But not a single sparrow can fall to the ground without your Father knowing it. And the very hairs on your head are all numbered. So don’t be afraid; you are more valuable to God than a whole flock of sparrows. (Matthew 10:28-31 NLT)
