You do not need to fear arrows that fly during the day. Our fears which terrorize us during the night can just seem to be worrying thoughts in the daytime. But again the Lord says we have no reason to fear. They cannot even find you!
He will cover you with his feathers. Does the picture of God as a mother hen disturb you or encourage you? When a hen takes her chicks under her wings, they are completely hidden from sight. Can you imagine yourself hidden in that safe, comfortable, warm place?
