Matthew 23:1 Then Jesus said to the crowds and to his disciples, 2 "The scribes and the Pharisees sit on Moses' seat, 3 so practice and observe whatever they tell you- but not what they do. For they preach, but do not practice. 4 They tie up heavy burdens, hard to bear, and lay them on people's shoulders, but they themselves are not willing to move them with their finger. 5 They do all their deeds to be seen by others. For they make their phylacteries broad and their fringes long, 6 and they love the place of honor at feasts and the best seats in the synagogues 7 and greetings in the marketplaces and being called rabbi by others. 8 But you are not to be called rabbi, for you have one teacher, and you are all brothers. 9 And call no man your father on earth, for you have one Father, who is in heaven. 10 Neither be called instructors, for you have one instructor, the Christ. 11 The greatest among you shall be your servant. 12 Whoever exalts himself will be humbled, and whoever humbles himself will be exalted.
Jesus uses the scribes and Pharisees to reveal the symptoms of sin, then He instructs the crowds and disciples how to live according to true righteousness in accordance with the truth. Matthew 23:8-12 teaches us how we should live.
We are to have one teacher, the Christ (vss 8, 10). We all learn the truth through the Scriptures, the teachings of the Christ (John 2:18-22). We are not to live our lives according to the traditions of man (Mark 7:6-9).
We are to acknowledge our Father is heaven. He is our provider and protector. We are all brothers and sisters. Paul writes in Ephesians 3:14-15, "For this reason I bow my knees before the Father, from Whom every family in heaven and earth is named."
We display greatness by serving others, not by being served. Paul captures this truth in Philippians 2:3-4. "Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others."
We are not to exalt ourselves, but humble ourselves and let God exalt us. We humble ourselves by depending on God alone for all things, including exalting us. We do not need to push ourselves forward or take the best seat to obtain honor as the scribes and Pharisees did.
