When Jesus is asked what we must do to have eternal life, he offers an interesting answer. First, he questions why they would ask him. Then he points them to the commandments. But none of us can obey the commandments well enough, especially when Jesus points out that we need to give away everything in pursuit of him. So what hope do we have? 

Jesus gives that hope elsewhere in Scripture when asked the same question. What must I do to have eternal life? Believe in Jesus!
