This article by Bill Fleming made me stop in my tracks when I first read it. How easy it is for our preaching to fall into the traps he mentions when we are not preaching the cross. It is very easy to simply exhort people to do better or to give them principles for improving their lives, with no need for Jesus and His cross.
We can exhort unconverted people to live Christian lives but not lead them to the cross so that it becomes possible.
At the end of the article, Fleming says, “The cross is the one, true remedy we have to offer a broken world. Let us be sure to display it proudly.”
