EVERYTHING HE DID WAS FOR US
"The Gospel teaches that Christ was born for our benefit and that everything he did and suffered was for us. As the angel says, 'I have good news for you, a message that will fill everyone with joy. Today your Savior, Christ the Lord, was born in David's city'. With these words, you can cleary see that he was born for all of us. He doesn't say a savior was born, but rather, 'your Savior, Christ the Lord was born'. In the same way he says, 'I have good news for you'. This joy is for everyone who has this kind of faith."
Martin Luther, Faith Alone.
