Pastors, wanting to 'contextualize' the gospel have turned to profanity ('swear words') in their sermons. These contextualizers, or relevantizers, simply do not believe that the gospel is "the power of God for salvation to everyone who believes." (Rom 1:16)
Phil Johnson writes about these types:
"See, I think this whole approach to ministry reflects a fatal lack of confidence in the power of the gospel itself. If we really believed the gospel is the power of God unto salvation, why would we think it necessary to dress the message in such shabby rags?"Preachers such as these simply bring disrepute to the gospel of Jesus Christ and show what they truly put their trust in for the salvation of their hearers!
