This is great (see the Tim Keller video below).  Humble Christian engagement with culture doesn’t involve Triumphalism (which is a broader way to define Dominionism, Dominion Theology), engaging culture for the sake of taking the reigns of societal power.  Nor Passive indifference, meaning – it’s not the job of the church to “mend the world” as Keller puts it..  The kingdom minded perspective is first seeing the value in all people, making room for their gifts (common grace) and yet engaging them within the culture by doing things counter-cultural and acting in accordance to the will of God.  Which is really nothing more than doing Matthew 5:14-16 – “You are the light of the world. A town built on a hill cannot be hidden. 15 Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. 16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.

Towards the end of the video, around the 20 minute mark Keller puts it this way:
“The gospel creates a kind of transformational leadership pattern” in which you give credit instead of taking it, in which you bear blame instead of making other people take it, in which you lift up rather than trample on, so you can get up the ladder.”……………….” A gospel shaped heart will create culturally engaged Christians that really will change the world.”
