The Lord Kept and Continues to Keep His Promise

Grace, mercy, and peace from God our Father and the Lord and Savior born to you this night Jesus Christ. Amen.

The People who walked in darkness have seen a great light. The first people to see that light were the people to ever live: Adam and Eve. With their sin, they had plunged both themselves into the darkness of sin and death. But God came to them with a light of hope. A promise. He would fix what they had done. He would restore creation. He would restore them. He would give them a Savior.

How was this to be done? The zeal of the Lord of Hosts will do this.

And tonight, we rejoice that the Lord has done it. Promise kept. In the city of David, the sleepy little Bethlehem, the child Isaiah prophesied would be born, the Wonderful, the Counselor, Mighty God, Everlasting Father, Prince of Peace. That child was born.

And then it was the shepherds turn to see the light. Go to Bethlehem and see, the angel told them, for there is the Christ, the Lord. Don’t let the swaddling clothese or the manger fool you. It really is Him, the prince of peace. Your savior.

For God always keeps his promises. Always.

I don’t. You don’t. Sometimes because I am a sinner and I fail. Sometimes because something happens and I no longer want to keep my promise, so I take it back instead. Sometimes I promise something I can’t do. But even when I want to keep a promise, and try mightily to do so, sometimes I just can’t. Maybe you got promised that someone would be here for Christmas, but they got stuck in bad weather. The Friends Song, I’ll be there for you, is a perfect example of how we wish we could be there for someone but really can’t always fulfill the promise.

But God… He always delivers. Because if He kept this promise, this promise of all promises, which other one would He not keep?

To us a child is born, to us a son is given because of his great zeal and love for you.

God sends His son into our sinful world, our world of sin and death, a world of broken promises. And He sends Him here to take our sin and our shames upon himself and He suffers our sins penalty. This babe which we adore this night, will be rejected by the very ones He is saving as He is condemned and crucified, and then even forsake by His Father. Doing it all for you out of his zeal and love for you and your salvation.

Many years before this God tested Abraham, we heard a little bit of that story in the Lessons and Carols service tonight, where God tested Abraham by asking him to sacrifice His Son Isaac. God eventually did not make Abraham go through the actual process of slaughtering his son. But the Son of God? That Son would not be spared. He died to save you. Just as the heavenly Father promised. And the Son did it willingly out of his love and zeal for you.

And if God did that and kept that promise for you, everything is else is easy, don’t you think? That’s how much God loves you. A love He doesn’t just speak, but a love that He acts upon. In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. Or in other words if you ever doubt whether God loves you, swaddling clothes a manger shows just how much he truly does. And it shows what He will do for you. He humbled Himself when He was born of a Virgin. And He humbled himself to the point of suffering death, death on a cross.

God had done a lot through the many years of waiting for this night. Wonderful works, great miracles, awesome power on display. Splitting seas apart, sending the bread from heaven for 40 years, defeating all kinds of armies. But nothing so great this; as a baby lying is swaddling cloths in a manger. This is his greatest work. His greatest miracle for you.

Sometimes He gets overshadowed by the lights of the world, or by the darkness in our hearts and lives – the struggles, the pains, cares, worries, broken promises that seem to come rolling in one after another.

And so it is exactly to us that Isaiah speaks tonight. Whether you’re in the darkness of the world’s lights, or the darkness of sin and sorrow and death, the people walking in darkness have seen a great light. Or as Paul puts it, the grace of God has appeared.

God has continued to give a lot. To people of old and to even to us. But no gift greater than this Son. The gift of a promise kept. The promise of life and salvation in this Son, Jesus our Lord.

Some gifts we receive get broken and thrown away. Some change the present and some change the future. But this gift of the Son born to the Virgin, changes us. It changes us from rebels to Sons, from sinners to saints, from being dead to being alive. For when the forgiveness of sins and love of God come to you and abides in you, how can that not change you?

Mary kept all these things and pondered them in her heart. As do we.

The shepherds returned, glorifying and praising God. As do we.

The zeal of the Lord of hosts will do this. And the Lord of hosts has. His zeal for you, His strong desire to love you and save you.

A zeal which now also lives in you, as we are the people of which Paul speaks, a people for his own possession who are zealous for good works. Because this Son now lives in you. His love and forgiveness live in you. And so too his zeal and good works.

So tonight we see again this great light. The grace of God, the glory of God, the Son of God, wrapped in swaddling cloths, lying in a manger. 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 Savior, which is Christ the Lord. The promise kept.

Amen.
