God's Secret Agents
He shall give his angels charge over thee, to keep thee in all thy ways. Psalm 91:11
A secret agent is one who seeks to protect his country, his king, or his president against evil forces that are opposed to the one he serves. The American Secret Service is charged with protecting the president of the United States. They do an excellent job, but even they will tell you that someone who is fiercely determined to assassinate the president could be successful.
God has His own secret agents---the angels. Unseen and unrecognized by the world, they never fail in their appointed tasks. Much has been written recently about angels--often not based on the Bible but on popular legends. But angels are real, and God has commanded them to watch over us. Only in eternity will we know how many accidents they prevented or how often they kept Satan's malicious spirits at bay. In the meantime, we can take comfort in their presence and thank God for the love He expresses for us through their service.
