Angels are powerful and serve God and can take on the form of a human being as evidenced by the Bible including:
Genesis 19:1, “And there came two angels to Sodom at even; and Lot sat in the gate of Sodom: and Lot seeing them rose up to meet them; and he bowed himself with his face toward the ground;” After Lot insisted the two angels enter his home, the men of Sodom beat on the door saying they wanted to “know” Lot’s two guests. The angels “smote the men that were at the door of the house with blindness.” Lot his family were removed from danger by the two angels before fire and brimstone could destroy Sodom and Gomorrah until.
When the king of Syria sent men to capture Elisha he calmed his servant Kings 6:16, “And he answered, Fear not: for they that be with us are more than they that be with them.” Then the servant was treated to an extraordinary and supernatural experience. Kings 6:17, “And Elisha prayed, and said, LORD, I pray thee, open his eyes, that he may see. And the LORD opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha.”
Isaiah 37:36, “Then the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses.” Also 2 Kings 19:35.
Daniel had a vision of the archangel Gabriel, Daniel 10:5-6, “Then I lifted up mine eyes, and looked, and behold a certain man clothed in linen, whose loins were girded with fine gold of Uphaz: 6 His body also was like the beryl, and his face as the appearance of lightning, and his eyes as lamps of fire, and his arms and his feet like in colour to polished brass, and the voice of his words like the voice of a multitude.”
Two angels appeared at the empty tomb, Luke 24:3-4, “3 And they entered in, and found not the body of the Lord Jesus. 4 And it came to pass, as they were much perplexed thereabout, behold, two men stood by them in shining garments”
An encounter with an angel, I think so. I grew up in Michigan, the youngest of three children. We lived in a big old frame house that was very expensive to heat. We have plenty of blankets upstairs but no heat as no registers. Winter mornings the three of us kids would race downstairs and the first one down would to get to sit on the register in the living room and warm up.
I rarely was the first to get to the cozy register, however, one morning I was downstairs first and was soaking up the warmth in my flannel nightie, years before flame resistant materials were common. I heard an audible voice behind me telling me to get up and I immediately stood up a distance from the register.
Apparently, there was coal dust in the vent to the register because a flame shot out about 3 feet. The flame lasted a very short time, but I remember it distinctly. I told my mom about it, but she didn’t seem to believe me. All these decades later I remember turning around and seeing the flame. So, was this the devil trying to destroy a child of God before I was old enough to oppose him?
Angels are real and can take the form of a human or be a voice of warning. Angels are found throughout the Bible, Archangel Michael as the warrior of God and Gabriel as a messenger of God.
