Why did Jesus come?

Maybe you have asked this question before or maybe someone has asked you this question. 1 John is not often a book we might hear preached about it in this season of advent. But yet it for me has alot to say about the son of God who came in flesh.
So let me ask myself that question again:
Why did Jesus come?
1 John 3:8b gives us this answer:

"The son of God appeared appeared for this purpose to destroy all the works of the devil"
This is a really cool verse to remind ourselves as we approach the Lord in prayer.
We know this to be true and really give us a clue that the birth of Jesus is only a part of purpose. God is purposes continued to be revealed through his son after the birth. Right throughout his earthly ministry he continued to destroy the work of the devil. The final enemy to be defeated was death. Christ arose!

I came accross these verses within Luke within Zacharius' song, (John's father). It says:

Luke 1:74-75
"To grant that us that we being rescued from the hand of our enemies. might serve him with fear, in holiness and righteousness before him all our days"

Zacharius came to praise the God who had a taste of salvation.
