I see just the opposite happening in many places. Falling over themselves to be welcoming, affirming, relevant, accessible, seeker-friendly and all the rest, many churches are becoming less and less God's ekklesia, on a track toward becoming something He didn't call into being. I'm not thinking here of style but of substance.
From the apostle Paul:
For no one can lay a foundation other than that which is laid, which is Jesus Christ. Now if anyone builds on the foundation with gold, silver, precious stones, wood, hay, straw— each one's work will become manifest, for the Day will disclose it, because it will be revealed by fire, and the fire will test what sort of work each one has done. If the work that anyone has built on the foundation survives, he will receive a reward. If anyone's work is burned up, he will suffer loss, though he himself will be saved, but only as through fire.
Do you not know that you are God's temple and that God's Spirit dwells in you? If anyone destroys God's temple, God will destroy him. For God's temple is holy, and you are that temple. (1 Cor. 3:11-17)
