Simplicity does not mean watered-down, nor does it mean dumbed-down. Simplicity means as clear as possible.
Sometimes I get so grieved when I hear a pastor trying to “simplify” the gospel message for people. That definition usually means that they are removing any of the parts which might cause people to feel uncomfortable. That is not simplicity, but it’s a sell-out!
“All the simplicity in the world can do no good, unless you preach the simple gospel of Jesus Christ so fully and clearly that everybody can understand it. If ‘Christ crucified’ has not His rightful place in your sermons, and sin is not exposed as it should be, and your people are not plainly told what they ought to believe, and be, and do—your preaching is of no use!” (emphasis added)
Pastor, by all means make the gospel clear, but make sure people do hear all of the gospel.
