“Men and brethren, let me speak freely to you of the patriarch David, that he is both dead and buried, and his tomb is with us to this day. Therefore, being a prophet, and knowing that God had sworn with an oath to him that of the fruit of his body, according to the flesh, He would raise up the Christ to sit on his throne, he, foreseeing this, spoke concerning the resurrection of the Christ, that His soul was not left in Hades, nor did His flesh see corruption. This Jesus God has raised up, of which we are all witnesses. Therefore being exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He poured out this which you now see and hear. “For David did not ascend into the heavens, but he says himself: ‘The LORD said to my Lord, “Sit at My right hand, Till I make Your enemies Your footstool.” ’ “Therefore let all the house of Israel know assuredly that God has made this Jesus, whom you crucified, both Lord and Christ.”” Acts 2:29-36 NKJV
Here Peter affirmed, as did Christ on the road to Emmaus (cf. Luke 24:25-27), the events of Christ’s earthly life. Namely, that He would suffer, be crucified, and raised from the dead so as not to remain in the grave (v. 27). Christ was exalted to the second highest position in the universe (to the right hand of the Father) and given authority to rule (v.34). King David foresaw and prophesied this, fulfilling God’s promise of an eternal heir to his throne (cf. Psalm 132).
Having authority to rule delegated to Him by the Father, Jesus poured out His Holy Spirit at Pentecost to work more powerfully in the lives of His people. By the power of the same Spirit the people of God work to expand His kingdom and defeat His enemy, while Christ oversees at the Fathers right hand.
How is His Spirit manifested in you?
