Celebrating Christ’s mission accomplished and work ongoing

Sermon for the Festival of the Ascension

Acts 1:1-11  +  Mark 16:14-20

Today’s festival is one of the major festivals of Christ in the whole Church year. It ranks right up there with Christmas and Easter in importance. And yet, believe it or not, I still run into Christians, even Lutherans, who don’t know much about the Festival of the Ascension. So let’s make sure that everyone here, and everyone watching or listening, never (or never again) falls into that category!

As we learn in today’s reading from Acts 1, Jesus appeared on and off to His disciples over the course of 40 days after His resurrection on Easter Sunday. Twice that we know of in Jerusalem, twice that we know of in Galilee, and probably on several occasions we don’t about. He gave them final instructions about the kingdom of God, and about the coming of the Holy Spirit, telling them to wait in Jerusalem until the Spirit should come upon them with power. And then He met with them one last time, on the Mount of Olives, just outside Jerusalem, where Luke tells us that He lifted up His hands and blessed them, and as He was doing that, He was lifted up into the sky, He “ascended” into heaven until a cloud hid Him from their sight. And then, He was “gone.” Gone, in the sense that they never saw Him again. No one on earth ever saw Him again, except for the first martyr Stephen, who was allowed to see Jesus standing at the Father’s right hand before he died, and the apostle Paul, who was called and trained by Jesus directly.

Now, why is that something to celebrate, Jesus being “gone”? Well, as we heard Jesus say a couple of Sundays ago, it was to the Church’s advantage that He went away, because from heaven He would send them the Holy Spirit, who would accompany all the disciples of Jesus everyone in the world at once, whereas, when Jesus walked the earth, He only walked in one place at a time. The Spirit’s work is what would build the Church over the next 2,000 years.

But we celebrate the Spirit’s arrival on the Day of Pentecost, ten days from now. That’s not mainly what we celebrate today. Today we celebrate two things, mainly. We celebrate our  King’s victorious return to His heavenly Father after accomplishing His earthly mission. And we celebrate the beginning of the reign of Christ the King at the right hand of the Father.

That first thing, the King’s victorious return to His heavenly Father, is relatively simple. It doesn’t require too much commentary. Repeatedly Jesus tells His disciples that He was sent by God the Father, that He came from God the Father and would return to God the Father, that He had come down from heaven and would eventually return there. What does that mean?

Well, you and I don’t start out in heaven and then come down to inhabit our bodies. We don’t start with God and then return to God. The rest of us start to exist when we’re conceived. But th eternal Son of God was in heaven prior to His incarnation as a human being. He existed with a divine nature only, like the Father and like the Holy Spirit, without human flesh and blood, without a human nature at all. He “came down” from heaven by means of the incarnation, when He was conceived and took on a human nature in Mary’s womb, a human nature that coexists with His divine nature in one undivided Person, as the One who is both God and Man. That’s how He came down. And then, as both God and Man, He returned to the Father at His ascension. And He returned, not in defeat, but in victory, not in humility, but in glory. Because He had accomplished His mission, the mission which God had planned before the creation of the world, the mission on which the Father had sent Him some 34 years earlier. Jesus had led a perfectly holy, righteous, and sinless life. He had loved God and man without fail. He had tirelessly preached and ministered to the people of Israel, and to a few non-Israelites. He had suffered and died for the sins of mankind and had risen again. The mission was finished successfully. The reason for His coming down to earth was accomplished. Mission accomplished. Time to return to the Father.

And when He did, He received the glory He deserved. Glory as the Son of God, and also as the Son of Man. On the night before He night, Jesus prayed, O Father, glorify Me together with Yourself, with the glory which I had with You before the world was. That was His glory as the Son of God. But after accomplishing His mission to provide redemption for fallen man, He received glory also as the Son of Man, to whom saints and angels sing: Worthy is the Lamb who was slain to receive power and riches and wisdom, and strength and honor and glory and blessing!

And so we join our voices today in glorifying Christ the King, who accomplished His earthly mission to earn mankind’s salvation as the Son of Man, and who has now returned home victorious.

The King’s earthly mission was accomplished, but His heavenly work goes on. And so today we also celebrate the beginning of Christ’s work that He carries out at the right hand of God.

You heard in today’s Gospel that the Lord Jesus was received up into heaven, and sat down at the right hand of God. That’s a fulfillment of Psalm 110, which begins: The LORD said to my Lord, “Sit at My right hand, till I make Your enemies Your footstool.” It’s also a fulfillment of what Jesus said to the Jewish Sanhedrin as they were about to sentence Him to death: I say to you, hereafter you will see the Son of Man sitting at the right hand of the Power, and coming on the clouds of heaven.

What does it mean that Jesus sits at the Father’s right hand?

It isn’t a literal location relative to the Father’s literal location. There are those who claim (mainly the Calvinists and Reformed) that Jesus is physically located in a single place in heaven, from which He cannot move, and from which He certainly cannot cause His true body and blood to be present with the bread and wine of the Lord’s Supper. But they teach falsely. Yes, Jesus has a physical body. But the Father doesn’t! So how can Jesus sit at the right hand of the Father who has no physical hands? How can Jesus be restricted to a location next to the Father who has no physical location? No, to sit at the right hand of God means something else.

Sitting at the right hand of God means that Jesus has been exalted to the highest place, as both God and Man. It means that He has been given all authority in heaven and on earth. As Peter writes, Jesus has gone into heaven and is at the right hand of God, angels and authorities and powers having been made subject to Him. Yes, it means that He has come into His kingdom and has begun His reign as King, with all things in the universe placed under His feet, under His rule.

And what does that reign include?

Jesus once promised His disciples, On this rock—on this confession of Jesus as the Christ, the Son of the living God—I will build My Church. But that building only began to take place after His ascension. From the right hand of the Father, as part of His reign over all things, Jesus is building His Church.

He does that building through the office of the ministry. Jesus Himself is the Chief Minister, the High Priest over God’s Temple. As it says in the book of Hebrews, We have such a High Priest, who is seated at the right hand of the throne of the Majesty in the heavens, a Minister of the sanctuary and of the true tabernacle which the Lord erected, and not man. He Himself is working through earthly ministers whom He has sent and continues to send, as Peter said, God has exalted Him to His right hand to be Prince and Savior, to give repentance to Israel and forgiveness of sins. Through the preaching of Peter, through the preaching of all genuine ministers, through the Sacraments that Jesus instituted before His ascension, Jesus is the one, at the right hand of God, giving repentance and forgiveness, working through His Spirit to bring people to repent of their sins and to trust in Him who was delivered up for our sins and raised for our justification.

And as people are brought to faith, the Lord Jesus, sitting at the Father’s right hand, also justifies and intercedes for believers, pleading with the Father on our behalf. Paul writes, It is God who justifies. Who is he who condemns? It is Christ who died, and furthermore is also risen, who is even at the right hand of God, who also makes intercession for us.

What else? Paul writes that the Father seated Him at His right hand in the heavenly places, far above all principality and power and might and dominion, and every name that is named, not only in this age but also in that which is to come. And He put all things under His feet, and gave Him to be head over all things to the church, which is His body, the fullness of Him who fills all in all. So Jesus reigns as King. He reigns over all things, even over all “principality and power and might and dominion,” that is, the demonic forces of evil in the spirit-realm. He reigns over every government, over every institution, over every individual, over every germ, over every cell in our bodies, over nature, over gravity. He reigns invisibly. He reigns behind the scenes, until He returns to the earth. But we know for certain that every decision this King makes, whether we can see it or not, is for the good of His Church, as the head of a body makes decisions that are good for its own body.

Finally, remember what Jesus said to His disciples on the night before He died. I go to prepare a place for you. And if I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also. At the right hand of the Father, Jesus is preparing a place for every member of His holy Church, so that our home is ready when He returns in the same way His disciples saw Him go, visibly, coming down from heaven once again, for that final judgment that will mean eternal joy and peace for all who have believed in His name.

That, my Christian friends, is what Jesus’ ascension means for us today. It’s a celebration of Christ’s mission accomplished and also the beginning of His ongoing work, His work whose focus is our salvation. That’s what it’s about. And that’s why we celebrate it, and will continue to celebrate it, on the Thursday that always falls on the 40^th day after Easter. Amen.
