The sermon title is a bit of a pun on the question “are you of right mind?” To “have the mind of Christ” is to some degree to seem a bit crazy. The wisdom of Christ seems irresponsible and foolish. Just look at the things he said! We go to great lengths to dismiss or diminish his words because it makes us uncomfortable and also flies in the face of conventional wisdom. To be united with the mind of Christ opens up new ways to belong and become together and not just be “merely human.”
1 Corinthians 2:12-3:4 (ESV)
Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God. And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.
The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. The spiritual person judges all things, but is himself to be judged by no one. “For who has understood the mind of the Lord so as to instruct him?” But we have the mind of Christ.
But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ. I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready, for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way? For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not being merely human?
Matthew 23:1-12 (ESV)
Then Jesus said to the crowds and to his disciples, “The scribes and the Pharisees sit on Moses' seat, so do and observe whatever they tell you, but not the works they do. For they preach, but do not practice. 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. They do all their deeds to be seen by others. For they make their phylacteries broad and their fringes long, and they love the place of honor at feasts and the best seats in the synagogues and greetings in the marketplaces and being called rabbi by others. But you are not to be called rabbi, for you have one teacher, and you are all brothers. And call no man your father on earth, for you have one Father, who is in heaven. Neither be called instructors, for you have one instructor, the Christ. The greatest among you shall be your servant. Whoever exalts himself will be humbled, and whoever humbles himself will be exalted.
