Luke 2:14 “peace to all on whom God’s favor rests.”
The angel appearing to shepherds tells them God has great news for all people: “I bring good news of great joy that will be for all the people.”
The heavenly host reiterates what the initial angel said. The good news of great joy is going to take the form of peace—peace to all because the angels had already told them the joyous news was for everyone—all the people.
This idea remains large in the memory of mankind because deep in our psyche we sense there is something for us.
Peace—that nebulous, evasive quality that would be the response of nearly everyone if asked what they most want. This is certainly true of those attempting recovery from addition, experiencing grief over the death of a loved one, or making difficult decisions, and all the rest of us dealing with life.
The heavenly host—we can imagine a whole “host” of angels filling the sky, singing in unison, praising God for His amazing essence and announcing what he has designed for all people, since all people have found favor with Him. All are his favorites. All are intended to know the favor of the Lord, the peace of God.
