There is a prominence of angelic ministry at two places in Jesus' life: at his birth, and at his death and resurrection.
At Christmas we are reminded that there is a spiritual realm, and the existence of angelic beings who are very much interested in what's going on here.
The angels love the Son of Man, who is the Word made flesh.
"Great indeed, we confess, is the mystery of godliness: He was manifested in the flesh, vindicated by the Spirit, seen by angels, proclaimed among the nations, believed on in the world, taken up in glory," (1 Timothy 3:16)
"And again, when he brings the firstborn into the world, he says, 'Let all God's angels worship him.'" (Hebrews 1:6)
"...things into which angels long to look." (1 Peter 1:12)
So should we -- like these mighty beings -- see Jesus, look intently at all he has done, and worship him!
