Don't misunderstand what I am saying. I completely comprehend the sentiment. Live well, live as if you have been transformed by Christ. But for many people I know they live by this principle. Living to the best of their ability but never sharing the vital truths of the gospel with those whom they care about.
But living well, living a moral life, living with exceptional ethics is not the gospel. The gospel rather is the truth that we are all willing sinners who break the statutes of a holy and just God. This holy and just God loves the epitome of His creation, you and I, to the degree that He sent His one and only son, who never sinned Himself, to pay the penalty of our sins, which is something we could never do on our own. By His substitutionary death on the cross Jesus has made it possible for us to be called sons and daughters of our Creator God.
That is the gospel. Not right living!
How do you say all of this by "living right"? The answer is that you can't. Preaching involves words not actions. And no matter how many times you try and show someone the gospel through actions alone you will fail. To share the gospel you must open your mouth. To share the gospel means you must speak the gospel.
That does not mean that we do not try and live right, but if we are to make disciples our conduct alone will not cut it. To preach the gospel by its definition means we must use words. The question that remains is are you willing to do so, or are you going to continue to walk the path of least resistance and hope your actions are enough to get someone else into God's good graces.
