Answer: A carrot
I remember as a child being told that if I ate my carrots I would have good eye sight. I believed it at the time and so ate them. I liked them more raw than cooked but in reality wasn't too sure about my eyesight being helped because of it.
With the right eye sight we can right everything there is to see, but with bad eyesight we aren't going to see cry well and maybe even miss something that would otherwise give us the confidence to do that which we initially deemed impossible.
Elisha's servant, in 2 King's 6, didn't have eyes to see what Elisha saw when they find themselves surrounded by the king of Syria's army. The servant thought they were done for and even asked Elisha what they were going to do now.
But Elisha, whose mind was stayed on the Deliverer encouraged the servant: 2 King's 6:16 And he answered, Fear not: for they that be with us are more than they that be with them. 17 And Elisha prayed, and said, Lord, I pray thee, open his eyes, that he may see. And the Lord opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha.
When we are faced with seemingly insurmountable odds, keep your eyes on the Deliverer and see what He sees.
PRAYER: Father many times we will find ourselves surrounded by the army of our enemy ready to crush us, but may we have Your eyes to see what You see and know that there are far more for us than against us as we walk in Your way.
