"Sound doctrine divides, confronts, separates, judges, convicts, reproves, rebukes, exhorts, and refutes error. None of these things is very highly esteemed in postmodern thought. But the health of the church depends on our holding firmly to the truth, for where strong convictions are not tolerated, discernment cannot survive."

John MacArthur, The Truth War [Thomas Nelson], p. 198.
