I came across this in N. T. Wright's book Justification today. It captures the idea I have been preaching that we are to participate in God's Kingdom all around us:
"God, the Creator, must 'judge' the world in the sense of putting it right at the last--and... God has brought this judgment into the middle of history, precisely in the covenant-fulfilling work of Jesus Christ, dealing with sin through his death, launching the new world in his resurrection, and sending his Spirit to enable human beings, through repentance and faith, to become little walking and breathing advance parts of that eventual new creation." (251, emphasis added)
