There is a thrilling Old Testament story that best illustrates what it means to be kept by the power of God. We find it in 2 Kings 6.
Benhadad, king of Syria, declared war on Israel and marched against them with a great army. As his forces advanced, he often called his war counsel into his private chambers to plan the next day’s strategy. But the prophet Elisha, moved by the Holy Spirit, kept sending word to the king of Israel, detailing every move of the enemy troops. On several occasions, the Israelites escaped defeat because of Elisha’s warnings.
