God raised Israel's messiah from the dead. This that you see and hear is the work of God, the result of raising this Jesus from the dead, seating him at the right hand of God in glory and handing over to him the kingdom. God has made Israel's messiah, Lord of all, giving him the authority to pour out the Spirit, the effective power of the Kingdom of God.
This that you see and hear is God's keeping his promise to Abraham, that through Abraham all the nations of the earth will be blessed. It's what Mary and Zechariah sang about under the influence of the Holy Spirit,
he has shown mercy promised to our ancestors, and has remembered his holy covenant, the oath he swore to our ancestor Abraham.
This is God guaranteeing the world's future through Israel's messiah. Through Jesus, who pours the Spirit out on the 12, on Peter and James and John--and Mathhias, the freshly minted apostle, completer of the 12, the newest representative of the new Israel.
Jesus, pouring out the Spirit in Jerusalem, the city of David, Zion, God's holy mountain--not in Rome or Alexandria or Abilene or Searcy. Jerusalem. (more here)
And this has happened in the presence of devout Jews--devout Jews from every nation under heaven. Parthians, Medes, Elamites, oh my! God has placed devout Jews, people like Simeon and Anna in every corner of the globe, so that through Israel and the announcement of Israel's messiah, every nation on earth will be blessed.
This is God keeping this improbable story alive. This is God keeping faithfulness, breathing life in a story left for dead, raising it up, bringing it back to life, time and time again.
And here in a decisive way, in a way that leaves no doubt. In Israel's worst moment, putting to death God's annointed, the one attested by God through signs, deeds, wonders, in this lowest moment, God's greatest affirmation. He raised Israel's messiah from the dead and enthroned him forever, securing once and for all Israel's central role in the promise of God for all the world. Once and for all consoling Israel, redeeming Jerusalem, and through this, saving all nations.
This is the day that Simeon and Anna longed for, a line drawn by the Holy Spirit directly from their hearts to Pentecost. This is God's emphatic "yes" to all human longing for more, for fuller, for poured out, for extravagant mercy, for life without the threat of death, for the great and glorious day of the Lord.
