In the words prior to the DC Talk song "Jesus Freak" the narrator says a phrase that I will never forget as long as I live. He says "The greatest single cause of atheism in the world today is Christians, who acknowledge Jesus with their lips and walk out the door, and deny Him by their lifestyle. That is what an unbelieving world simply finds unbelievable." So what do we "Christians" have to do in order to have a better witness to the world? It's not simply sharing the message of salvation through faith in Jesus Christ. It's living our lives in accordance to what we believe. Nothing turns a person off more than a hypocrite. If someone were to tell you that you desperately need to do something, and they aren’t even doing it themselves, why in the world would you listen to what they had to say? It’s simple, the old “do as I say but not as I do” routine doesn’t work. If you want to be effective in ministry for Jesus Christ, you need to start by walking the talk.
