How many believers would still follow the teachings of their faith if all it offered was the command to do right for the sake of doing right?
There 'are' those who's motivation is simply to "do right for the sake of doing right." That's likely a healthier, more moral, more altruistic motivation than that of receiving an eternal reward. Jesus' love for us is His only motivation for doing what He did. And that alone, in turn, motivates many of His disciples likewise. They've learned (and are motivated) by His example.
