Jon explains what happens when moral relativism is followed to its logical conclusion.
So we were looking at the consequences of what happens when relativism creeps its way into our moral system of living. And one of the major consequences is, relativism undermines sin. We said, ultimately, if there’s no objective morality, there’s no sin. If there’s no sin, there’s no guilt. If there’s no guilt, there’s no need for a pardon. No pardon, well, no need for Jesus.
Ultimately, relativism undermines the gospel, friends. I think that’s important for us to take away tonight. It undermines the gospel. We see relativism in the Scriptures as at right at the end of Judges: “In those days, there was no king in Israel; everyone did what was right in his own eyes.”
Relativism also undermines the mission of Jesus. What’s the mission of Jesus, friends? We all should know it, right? “Go and make disciples of all the nations, baptizing them in the name of the Father, the Son, and the Holy Spirit, teaching them to observe all that I have commanded.” If relativism is true, that doesn’t matter. Jesus’ words are completely—they’re just a matter of opinion. Eh, you can do it or not. You know, teach what? Teach stuff that might be true for you but not for me? If relativism is true, there’s no obligation to do that.
We just need to think about it. I think it makes sense as we think about these things and how the ideas of relativism may have already crept into some of you guys as you sit there. You might be struggling with this. “Oh, wait a second, is he saying that what I believed is—maybe I should question it.” If relativism is true, then Christianity is just one of many true religions. That’s just a fact if relativism is true—choosing a religion is like choosing your favorite kind of ice cream.
