I believe in angels because the Bible says there are angels; and I believe the Bible to be the true Word of God… the Bible testifies that God has provided assistance for us in our spiritual conflicts. We are not alone in this world! The Bible teaches us that God's Holy Spirit has been given to empower us and guide us. Also, the Bible – in nearly three hundred different places – also teaches that God has countless angels at His command.

Furthermore, God has commissioned these angels to aid His children in their struggles against Satan....If the activities of the devil and his demons seem to be intensifying in these days, as I believe they are, should not the incredibly greater supernatural powers of God's holy angels be even more indelibly impressed on the minds of people of faith? After all, references to the holy angels in the Bible far outnumber references to Satan and his subordinate demon. If you are a believer, expect mighty angels to accompany you in your life experiences...I also believe in angels because I have sensed their presence in my life on special occasions."

The first Call of Christmas…is a Call to Prepare.

”Luke opens his gospel with a long, formal sentence, like a huge stone entrance welcoming you impressively to a large building. Here, he is saying, is something solid, something you can trust. Readers would know they were beginning a serious, well-researched piece of work. This wasn't a fly-by-night or casual account. It would hold its head up in the world at large." N.T. Wright

"Gabriel is primarily God's messenger of mercy and promise. He appears four times in the Bible, always bearing good news (Daniel 8:16, 9:21, Luke 1:9, 26). We may question whether he blows a silver trumpet, since this idea arises from folk music and finds only indirect support in Scripture.
But the announcements of Gabriel in unfolding the plans, purposes, and verdicts of God are of monumental importance. Gabriel first appears in the New Testament in Luke 1. He identifies himself to Zachariah, announces the birth of John the Baptist, and describes his life and ministry as the forerunner of Jesus." Billy Graham - Angels: God's Secret Agents

The Call of Christmas from Gabriel to Zechariah
is a Call to Prepare the way of the Messiah and his upcoming arrival.

"The story is about much more than Zechariah's joy of having a son at last or Elizabeth's exultation of being freed from the scorn of the mother's in the village. It is about the great fulfillment of God's promises and purposes. But the needs, hopes and fears of ordinary people are not forgotten in this larger story, precisely because of who Israel's God is – the God of lavish, self-giving love...When God acts on the large scale, he takes care of smaller human concerns as well." NT Wright

But preparing our hearts to encounter the Savior is something
that is a meant to be life-changing both for our neighbors and us.

How do you need to respond to this Call to Prepare during the Christmas season?
