The past two sermons at Redeemer have been on the Resurrection and Ascension of Christ. The Resurrection and Ascension were the final act in the inauguration of the “Redemptive” Kingdom. (I would submit the inauguration of the Kingdom began when Jesus’s earthly ministry started (Matt. 4:17) and was completed with the Resurrection and Ascension (Matt. 28:18). We await the consummation of the Kingdom which will happen at the Return of Christ (Rev. 21:5-6). I say “Redemptive” because God is Sovereign over everything (Ps. 103:19) and all the earth is His domain. However, God is making a new people (Kingdom) through Christ, the second Adam. See the distinction in the quote below.) I came across this summary statement of the Kingdom by D.A. Carson this week and thought it was helpful. Carson wrote:
Now that Christ has risen from the dead and is seated at the Father’s right hand, both these senses of “kingdom,” the universal and the redemptive, persist. On the one hand, all authority is given to Christ in heaven and on earth (Matt. 28:18). All of God’s sovereignty is now mediated through Christ (1 Cor. 15:24-28). In that sense, Christ’s kingdom is inescapable. On the other hand, Christ’s kingdom is regularly conceived of as that subset of his total reign under which there is transformed, eternal life. We cannot see or enter this kingdom apart from the new birth (John 3:3, 5). This kingdom is already in operation, permeating this lost world the way yeast permeates a lump of dough (Matt. 13:33). It is the supreme treasure to be pursued (Matt. 13:44-46). And at its consummation, every knee will bow and every tongue confess that Jesus is Lord, to the glory of God the Father (Phil. 2:9-11).
The above is from Carson’s book, Jesus the Son of God.
