Angels are spirits on mission, and that mission is God's. So, we can say that God, out of his love, sends angels to aid us in our redemption. Angels are sent for our redemption, and that redemption leads us all the way into the heights of worship.
Scot McKnightIn the Bible angels speak and humans speak back to them. This is the case with Mary in Luke 1. The angel speaks, Mary questions, and it goes back and forth. Abraham speaks with angels. So I would contend the Bible has enough evidence of angels speaking and humans speaking that speaking with an angel today would be reasonable. I've heard enough stories and read such that confirm that Christians today do speak with angels.
Scot McKnightAngels, inasmuch as they come from the Throne Room of the Thrice-holy God, usher us into the presence of God once removed and such encounters with God are more powerful and overwhelming than ordinary moments with God.
Scot McKnightSome think we each have a guardian angel while others think we don't have an assigned guardian angel, while yet others think God at times - but not always and not by assignment to each of us - sends an angel on a mission of guarding. The Bible's evidence that each of us has a specific, assigned guardian angel is not as solid as some think, so I'm with those who think sometimes God sends guardian angels but that we don't have a specific guardian angel.
