Mark 10:42-45: 42 Jesus called them over and said to them, “You know that those who are regarded as rulers of the Gentiles dominate them, and their men of high positions exercise power over them. 43 But it must not be like that among you. On the contrary, whoever wants to become great among you must be your servant, 44 and whoever wants to be first among you must be a slave to all. 45 For even the Son of Man did not come to be served, but to serve, and to give His life—a ransom for many.

Ephesians 5:1-2, 15-21 5 :1 Therefore, be imitators of God, as dearly loved children. 2 And walk in love, as the Messiah also loved us and gave Himself for us, a sacrificial and fragrant offering to God.. . . . 15 Pay careful attention, then, to how you walk—not as unwise people but as wise—making the most of the time, because the days are evil. So don’t be foolish, but understand what the Lord’s will is. And don’t get drunk with wine, which leads to reckless actions, but be filled by the Spirit: speaking to one another in psalms, hymns, and spiritual songs, singing and making music from your heart to the Lord, giving thanks always for everything to God the Father in the name of our Lord Jesus Christ, submitting to one another out of reverence for Christ.

Galatians 3:27-28: For as many of you as have been baptized into Christ have put on Christ like a garment. There is no Jew or Greek, slave or free, male or female; for you are all one in Christ Jesus.

Colossians 3:9-11: (9) Do not lie to one another, since you have put off the old self with its practices and have put on the new self. You are being renewed in knowledge according to the image of your Creator. In Christ there is not Greek and Jew, circumcision and uncircumcision, barbarian, Scythian, slave and free; but Christ is all and in all.
