God has angels who constantly patrol the earth, reporting back to Him at His throne. Angels have served as messengers. The Bible tells that Gabriel appeared to Zachariah, the father of John the Baptist, and to Mary the mother of Jesus. Let's look at one example. Rhoda, a young girl who came to see who was at the gate, was shocked to find Peter, who had been supernaturally released from prison by an angel.
Angels often take on the form of men.
Abraham, Lot, Haga, Moses, Manoan, Gideon, and Elijah are just a few who have had first hand encounters with angels. 2 tells us that man is, in his physical state, a little lower than the angels and that even Jesus Christ, as a human being, was made a lower than the angels. Not many of us think of angels as fellow servants, if we think of them at all. Whoever will be chief among you let him be your servant . That puts a new light on the task that God has assigned the angels.
