An angel sent by God revealed to Joseph that the baby his betrothed Mary was expecting was the promised Savior.
Jesus is the Savior
And the birth of Jesus Christ took place like this: after his mother Mary was betrothed to Joseph, before they were united, she was found not empty of the Holy Spirit. And her husband Joseph, because he was righteous and did not want to expose her, thought to leave her secretly. But when he thought of this, an angel from God appeared to him in a dream and said:
"Joseph, son of David, do not be afraid to take Mary as your wife, because what is conceived in her is from the Holy Spirit.
She will give birth to a Son, whom you will call Jesus, because it is He who will save His people from their sins."
The Holy Gospel from Matthew 1:18-25
After the birth of Jesus, again an angel of the Lord revealed to the shepherds that the Savior was born.
And she gave birth to her firstborn Son, wrapped him in swaddling cloths and laid him in a manger, because there was no room for them in the inn.
In the same place there were shepherds who lived in the fields and kept a night watch over their flock. And an angel of the Lord stood before them, and the glory of the Lord shone upon them, and they were greatly afraid. But the angel said to them:
"Fear not, for, behold, I bring you good tidings of great joy, which shall be to all people. For there is born unto you this day in the city of David a Savior, who is Christ the Lord. And this shall be your sign: you shall find a babe wrapped in swaddling clothes and lying in manger."

Jesus is the High Priest Who offered Himself as a sacrifice for the sins of the people
Under the Old Testament, God chose men as high priests to bring before Him animals without blemish as sacrifices for their own sins and for the sins of the people.
Under the New Covenant, God chose Christ as High Priest, who offered Himself once only as a sacrifice without blemish to God to make atonement for the sins of His elect.
And because Christ came as the high priest of the good things to come, He entered through the greater and more perfect tabernacle, not made with hands, that is, not of the present creation, once for all into the sanctuary, and not with the blood of goats and of calves, but with His own blood, and obtained for us eternal redemption. For if the blood of goats and bulls and the ashes of a heifer, with which the unclean were sprinkled, sanctifies for the cleansing of the body, how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God!
Hebrews 9:11-14
For we needed such a high priest: holy, innocent, blameless, separated from sinners and exalted above the heavens, Who does not need to sacrifice every day, like those high priests, first for his own sins, then for the sins of the people, because he did this once and for all by offering Himself. For the law appointed weak men as high priests, and the words of the oath which was after the law appointed the Son, who was perfected forever.
Hebrews 7:26-28
For Christ entered not into a sanctuary made with hands, an image of the true, but into the heavens themselves, to appear already before the face of God for us, and not to offer Himself many times, as the high priest enters the sanctuary every year with other people's blood (otherwise He must have suffered many times since the creation of the world), and in action at the end of the ages appeared once to take away sin by offering Himself as a sacrifice.
Hebrews 9:24-26
Jesus is the Lamb of God - the sacrifice to atone for our sins

This He did to show His righteousness in forgiving the sins committed before when God was longsuffering.
Epistle of the Apostle Paul to Romans 3:23-25
Knowing that it was not with perishable things - silver or gold - that you were redeemed from the vain life handed down to you by your fathers, but with the precious blood of Christ, as of a lamb without blemish and pure.

The Holy Gospel of John 3:16
Because Christ also suffered once for sins, the Just for the unjust, to bring us to God, being put to death in the flesh, but quickened in the spirit.
The First Epistle of the Apostle Peter 3:18
Because hardly anyone will be found to die even for a righteous person (although it is possible to dare someone to die for the good). But God commends His love to us in that, while we were yet sinners, Christ died for us.
Epistle of the Apostle Paul to Romans 5:7-8
Because of His love for us, Jesus humbled Himself and willingly gave His life as a sacrifice for our sins.
As the Father has loved Me, so have I loved you. Abide in My love. If you keep My commandments, you will abide in My love, just as I have kept My Father's commandments and abide in His love…
Greater love has no one than this, to lay down one's life for one's friends.
You are My friends if you do what I command you.
The Holy Gospel from John 15:9-10,13-14
