Example:
In 2 Kings 6 there is a compelling story of the city of Elisha.
They are surrounded by a powerful army in the night. It is their Doom's Day and all are about to die. Elisha's servant wakes up and walks outside and can only see the horses and soldiers of those that are about to kill them in the mountains so he to turns to Elisha, God's prophet, for help.
Vss 16-18 "So Elisha answered, "Do not fear, for those who are with us are more than those who are with them."
Then Elisha prayed and said, "O LORD, I pray, open his eyes that he may see."
And the LORD opened the servant's eyes and he saw; and behold, the mountain was full of horses and chariots of fire all around armies in the mountains!
