"Teacher," he asked, "which is the greatest commandment in the Law?" Jesus answered, " 'Love the Lord your God with all your heart, with all your soul, and with all your mind.' This is the greatest and the most important commandment. The second most important commandment is like it: 'Love your neighbor as you love yourself.' The whole Law of Moses and the teachings of the prophets depend on these two commandments."
