This weekend, Pastor Rick Warren will speak at the Islamic Society of North America's annual convention.

To critics of Warren, who think it's wrong on the face of the matter for him to speak at an event sponsored by Muslims, I say: Wait until you hear what Warren says.

I don't say that with any kind of inside information. I say it based on the fact that in the Bible, proponents of the gospel seem never to have hesitated to go anywhere with their proclamation. I appreciate Rick Warren's boldness, and I pray for his faithfulness.

Here's the test: If Warren shows up at the Muslim gathering and soft-pedals the truth, and talks only about how important it is for us to "get along," then evangelicals should hold him to account. But if he is as typically forthright as he usually is, we should thank God for the opening and pray that the Lord will prosper Warren's words.

And the rest of us should get busy and look for similar opportunities.
