And the genesis of Jesus, the Christ was so: His mother Mary, having been betrothed to Joseph, before their coming together, she was found having in womb of the Holy Spirit. And Joseph, her husband, was righteous and did not wish her to be disgracefully exposed, intended privately to divorce her. And having thought about these things, look, an angel of the Lord according to a dream appeared to him saying, "Joseph, son of David, do not be afraid to take Mary your wife; for the one begotten in her is out of the Holy Spirit. And she will bear a son, and you will call His name `Jesus'; for this One will save His people from their sins." And the whole of this happened in order that it be fulfilled, the thing spoken by the Lord through the prophet, saying, "Look, the virgin will have in the womb and will bear a son, and they will call his name, Immanuel" which is translated "with us, God". And Joseph, having risen from the sleep, did as the angel of the Lord commanded to him, and took along his wife and did not know her until she bore a son; and he called His name `Jesus'.
What's in a name? A rose by any other name would still smell the same, as Shakespeare reminds us. But sometimes a name is highly significant. It's very important for the Christ-child, because His name reveals to us just Who He is, and what He is to accomplish! Which is why, in our story today, the second person of the Trinity receives not one but two names. But before we get into the importance of these two names, we must first consider just Who this Christ-child is and how He came to be so...
Jesus obviously didn't come into this world in the normal fashion. He had a mother who became pregnant with him while still a virgin. She was "betrothed" and considered married to Joseph because the vows were in those days at the engagement, not at the marriage ceremony. But they hadn't come together yet. They didn't know one another in the biblical sense, so there was no way Joseph could be the father of this baby boy. So Joseph, an upright guy, wanted to divorce Mary quietly, shamefree.
Then God's angel comes to him in a dream to explain what has happened. Mary is pregnant, but not from a man. She became with child from the Holy Spirit! No human male was Jesus' father. God the Father was His daddy! This was very important, since human fathers passed on sin and death to their children, from generation to generation. But Jesus had no human father, so He was sin-free. He had no "old adam" in Him to give in to sinning like you have. Jesus had a pure and undefiled flesh!
That's precisely why the Christ is given the name "Jesus", because it means Savior. He is called Jesus because He has come to save His people from their sins. That includes you. The Christ-child was born sin-free to earn eternal life for you by his righteous obedience under God's Law. As a human, Jesus was made subject to keeping God's commandments, and he did it perfectly. He was the only one to live out His life on earth without sinning, thus being the only one worthy of life eternal.
But Jesus didn't come to save Himself, but to save His people from their sins. This is why He came in the likeness of sinful flesh, so that He could bear sin in His Own body. Not His Own sins, since He was perfect, but Jesus came to earth to bear your sins in His own flesh on the tree of Calvary. Jesus, Who knew no sins of His Own, made Himself incarnate to become your sins on the cross. He suffered the wages of your sin, dying your death to save you from being forsake by your heavenly Father.
Yes Jesus became man, in the flesh to take your sins and their punishment as His Own. For liars, Jesus became a liar. For those who lose their tempers, Jesus became a temper-loser. For thieves Jesus became a thief. For the unfaithful Jesus made Himself to be unfaithful. For gossips Jesus became a gossip. For the foul-mouthed Jesus became foul-mouthed. He died as the transgressor.
But the incarnate second Person of the Trinity isn't just given the human name of Jesus. He is also given another name: "Immanuel". This name is just as important for the Christ, because it is a divine name. It means "God–with us!" With this name, it is revealed to us just what is happening in Mary's womb. It's not just a human baby in there. It's fully God as well! As God, this Christ-child has the power to do what only God can, forgive sins, save souls, deliver from death and the devil, and bestow eternal life!
This Immanuel is God-with us now, and until the end of the age. The incarnate Jesus was with you at your baptism, washing your sins from you to Himself at Calvary. He is in His Word proclaimed, entering your ear as you hear that He has come to save you from your sins. He is in the bread and wine, giving you his ever-living body and life-giving blood for your forgiveness, life and salvation. Jesus is Immanuel, God-with you in the voice of your Pastor forgiving you absolutely when you confess.
