The young salesman was disappointed about losing a big sale, and as he talked with his sales manager he lamented, "I guess it just proves you can lead a horse to water but you can’t make him drink." The manager replied, "Son, take my advice: your job is not to make him drink. Your job is to make him thirsty."
So it is with evangelism. Our lives should be so filled with Christ that they create a thirst for the Gospel.
