Sermons on almost every topic

Found this story recently. It's a sobering warning:

Dietrich Bonhoeffer studied for a year in New York City. He visited a number of churches there, and this is what he concluded: "One may hear sermons in New York upon almost any subject; one only is never handled, namely, the gospel of Jesus Christ, of the cross, of sin and forgiveness."

Hope that's not true of us.
