2 Kings 6: 15 "And when the servant of the man of God was risen early, and gone forth, behold, an host compassed the city both with horses and chariots. And his servant said unto him, Alas, my master! How shall we do?”
I heard a story about a young lady who was at the vet with her pet, and in walks a man with a yellow Labrador Retriever. It looked exactly like the dog that someone had given her brother. She heard the man mention the dog’s name, it was the exact same name. Then he mentioned the age, it was the exact same age. This lady was positive that this man stole her brother’s dog, or perhaps her brother gave his dog away. So she called her brother just to make sure, and the yellow Lab was sitting right there with him. Ha!
Similarly, in 2 Kings 6:15, Elisha's servant judged what he was seeing with his natural eyes. He saw an army of horses and chariots surrounding the city, and asked his master, "What are we going to do?" Recognizing this, Elisha prayed that the Lord would open his eyes that he might see, truly see with his spiritual eyes. Immediately, the servant saw the chariots of fire and angels all around the city!
Same thing happened when the Lord lead Samuel to the house of Jesse to anoint the new king. Jesse presented him with his son Eliab, and Samuel said to himself, surely this is God’s anointed! God’s response, "Do not look on his appearance or on the height of his stature, because I have rejected him. For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart." In other words, don’t be impressed, looks aren’t everything, keep your eyes fixed on what God has for you…you can’t judge a book by its cover!
