Mark 12:28-31

One of the teachers of the Law of Moses came up while Jesus and the Sadducees were arguing. When he heard Jesus give a good answer, he asked him, “What is the most important commandment?” Jesus answered, “The most important one says: ‘People of Israel, you have only one Lord and God. You must love him with all your heart, soul, mind, and strength.’ The second most important commandment says: ‘Love others as much as you love yourself.’ No other commandment is more important than these.”
