The Greatest Commandment

34 Hearing that Jesus had silenced the Sadducees, the Pharisees got together. 35 One of them, an expert in the law, tested him with this question: 36 “Teacher, which is the greatest commandment in the Law?”

37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ 38 This is the first and greatest commandment. 39 And the second is like it: ‘Love your neighbor as yourself.’ 40 All the Law and the Prophets hang on these two commandments.”

Matthew 22:34-40 (NIV)

The Heart of Man

14 After He called the crowd to Him again, He began saying to them, “Listen to Me, all of you, and understand: 15 there is nothing outside the man which can defile him if it goes into him; but the things which proceed out of the man are what defile the man. 16 [If anyone has ears to hear, let him hear.”]

17 When he had left the crowd and entered the house, His disciples questioned Him about the parable. 18 And He *said to them, “Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, 19 because it does not go into his heart, but into his stomach, and is eliminated?” (Thus He declared all foods clean.) 20 And He was saying, “That which proceeds out of the man, that is what defiles the man. 21 For from within, out of the heart of men, proceed the evil thoughts, fornications, thefts, murders, adulteries, 22 deeds of coveting and wickedness, as well as deceit, sensuality, envy, slander, pride and foolishness. 23 All these evil things proceed from within and defile the man.”

Mark 7:14-23 (NASB)
