To whom did the angel of the Lord announce the birth of Jesus?

 

"And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord." - Luke 2:8-11 KJV

"And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger." - Luke 2:12 KJV

"And suddenly there was with the angel a multitude of the heavenly host praising God, and saying, Glory to God in the highest, and on earth peace, good will toward men." - Luke 2:13-14 KJV

The angel of the Lord made the great announcement of the birth of Christ the Lord to shepherds and their flock. (Exodus 3:1-2, Psalm 78:70-71, Jeremiah 23:3-4, Jeremiah 3:15, John 21:15-17, John 10:1-5, 7, 1 Peter 5:1-4, 1 Peter 5:1-4, Acts 20:28.)  

"And it came to pass, as the angels were gone away from them into heaven, the shepherds said one to another, Let us now go even unto Bethlehem, and see this thing which is come to pass, which the Lord hath made known unto us. And they came with haste, and found Mary, and Joseph, and the babe lying in a manger. And when they had seen it, they made known abroad the saying which was told them concerning this child." - Luke 2:15-17 KJV

The shepherds were witnesses. They told everyone what had happened and what the angel had said to them about this child. The angel told them he was bringing good tidings of great joy, which shall be to all people. This child that was born is the Saviour, Christ the Lord. He came to bring peace to the world. (Acts 1:8, Acts 5:32, Acts 22:14-15, Matthew 24:14, Mark 13:9, 1 Corinthians 1:6, 1 Corinthians 2:1, 2 Corinthians 1:12, 2 Thessalonians 1:10, 1 Timothy 2:6, 2 Timothy 1:8, Acts 13:52, Romans 14:17, Romans 15:13, 1 Peter 1:8, Jude 1:24-25).

Jesus brought peace to the world by His gospel – His death, burial, and resurrection. (Colossians 1:20-23). Because of this, it is called the gospel of peace.  (Romans 10:15, Ephesians 6:15). We claim His peace when we apply His gospel to our life. (John 20:19-23, Acts 10:36-43, Isaiah 9:6-7). Repentance is death to sin. Water baptism in the name of Jesus is burial of old sinful nature. Holy Ghost infilling is resurrection to new life. (Acts 2:38, Acts 2:4).

"And the shepherds returned, glorifying and praising God for all the things that they had heard and seen, as it was told unto them." - Luke 2:20 KJV
