Perhaps the tension remains because we should desire the things of God, not the things of this world. Is that truth a reality for us? Not always. Is it ideal? Yes.
So if the post-modern culture says, "If it works, then it's true" . . . where does that leave us? I think we need to revisit God's idea of culture starting today!
"Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. The rains came down, the streams rose, and the winds blew and beat against the house; yet it did not fall, because it had its foundation on the rock."
-Jesus, Matthew 7:24-25
