25 Now there was a man in Jerusalem called Simeon, who was righteous and devout. He was waiting for the consolation of Israel, and the Holy Spirit was on him.
26 It had been revealed to him by the Holy Spirit that he would not die before he had seen the Lord’s Messiah. 27 Moved by the Spirit, he went into the temple courts. When the parents brought in the child Jesus to do for him what the custom of the Law required, 28 Simeon took him in his arms and praised God, saying:
29 “Sovereign Lord, as you have promised,
you may now dismiss[a] your servant in peace.
30 For my eyes have seen your salvation,
31 which you have prepared in the sight of all nations:
32 a light for revelation to the Gentiles,
and the glory of your people Israel.”
33 The child’s father and mother marveled at what was said about him.
34 Then Simeon blessed them and said to Mary, his mother: “This child is destined to cause the falling and rising of many in Israel, and to be a sign that will be spoken against, 35 so that the thoughts of many hearts will be revealed. And a sword will pierce your own soul too.”
36 There was also a prophet, Anna, the daughter of Penuel, of the tribe of Asher. She was very old; she had lived with her husband seven years after her marriage, 37 and then was a widow until she was eighty-four.[b] She never left the temple but worshiped night and day, fasting and praying. 38 Coming up to them at that very moment, she gave thanks to God and spoke about the child to all who were looking forward to the redemption of Jerusalem.
Do you see what their Christmas celebration was like? They had nothing (of this world). They had everything (Jesus Christ).
Regarding prophecies, His first coming fulfilled many and every promise from the OT, (e.g. Gen 3 & 49; Deut 18; Ps 2 & 22; Is 7, 9, 52, & 53; Dan 9; Mic 5; Zech 11 & 13; Mal 3.) The Bible has far more to say about His second coming than His first.
The message of Christmas is clear: He’s come. His name is Jesus. He alone can save you from your sins. He will be back. Be sure you’re ready when He returns.
