When an attendant of the man of God rose early in the morning and went out, an army with horses and chariots was all around the city. His servant said, “Alas, master! What shall we do?” He replied, “Do not be afraid, for there are more with us than there are with them.”
2 Kings 6:15-16
During WWII a passenger ship sailed from Great Britain to New York.
The Captain of the ship was afraid of enemy vessels and asked for the advice of a British Admiral. The Admiral calmly assured the Captain that no matter what happened he should sail his ship straight ahead. "Do not take any detours and continue onward, always heading straight toward the intended mark," he said.
After several days of sailing across the Atlantic Ocean which was filled with submarines and enemy vessels, the Captain spotted an enemy destroyer off his forward bow. Nervously he called for assistance. A calm voice replied, "Keep on straight and do not detour. Everything will be just fine."
After a few more days the ship pulled safely into the harbor of New York City. Shortly after docking, the great British battleship Man-O-War pulled into port behind the passenger vessel. The Captain realized that while he had not seen the great battleship, she had been there-- sailing ready to come to their defense should it prove necessary.
Similarly, in 2 Kings 6:15-17
15 When an attendant of the man of God rose early in the morning and went out, an army with horses and chariots was all around the city. His servant said, “Alas, master! What shall we do?” 16 He replied, “Do not be afraid, for there are more with us than there are with them.” 17 Then Elisha prayed: “O Lord, please open his eyes that he may see.” So the Lord opened the eyes of the servant, and he saw; the mountain was full of horses and chariots of fire all around Elisha.
Elisha opens the servant's eyes to see the army of God was with them because the Syrian army had surrounded the city in which Elisha was staying. When the servant sees that the army of God is larger than the army surrounding the city he recognizes that God stands by for us! God bids us to go forward toward the mark, the goal, and within God's Purpose!
