There is certainly a difference between "saying" the correct words and "doing" the just deeds. Jesus tells the story of The Good Samaritan, about an injured traveller, and the reactions of various people whom he comes in contact. The story's inference is made very clear - it’s what goes on in this human "interaction" (or, in a lack of any interaction) that defines our eternal destiny.
In this story, our attention is directed to the hated Samaritan, who was an outcast in Jewish circles. He is the only one who answers to the need for help by a fellow human being. Others don’t respond, deciding to follow rigidly the rule about ritual cleanliness. By forcing the lawyer to verbally identify who his "neighbour" really is, Jesus has successfully moved his hearers away from ritual rigidity into facing the reality of the obligation of universal love. In this way, Jesus has thus set out a new world view for his listeners - a world without racial or ethnic boundaries of any kind.
St. Cyril of Alexandria said (in effect) that you can tell the state of your heart by the questions you ask. If the lawyer had to ask who his neighbour was, then he was already lacking true love in his heart for his fellow man. If a person is empty of love for neighbour, then they are certainly empty of love for God. Of course, the text even tells us that the man was "trying to justify himself," indicating he had a problem with pride of heart.
The story makes us wonder if there a hated Samaritan in our own life, and therefore what does that say about your love of God about you and eternal life.
