What do angels do...? Over the ages people have referred to angels as messengers of God who rescue, give aid, and bless us with calm and serenity. They warn, guide, teach, and answer our prayers giving us hope. Perhaps the calm and peaceful serenity that generously descends over us on occasion is the presence of an angel. A spontaneous and complete hush that comes over a crowded room has often been referred to as an angel passing through.
