Mark 12:28-31

28Now one of the experts in the law came and heard them debating. When he saw that Jesus answered them well, he asked him, “Which commandment is the most important of all?”

29Jesus answered, “The most important is: ‘Listen, Israel, the Lord our God, the Lord is one.

30Love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.’

31The second is: ‘Love your neighbor as yourself.’ There is no other commandment greater than these.”
