Matthew 20:25-28 (NIV)

25 Jesus called them together and said, “You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them. 26 Not so with you. Instead, whoever wants to become great among you must be your servant, 27 and whoever wants to be first must be your slave— 28 just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.”

James 2:1,2 (NIV) - Favoritism Forbidden

1 My brothers and sisters, believers in our glorious Lord Jesus Christ must not show favoritism. 2 Suppose a man comes into your meeting wearing a gold ring and fine clothes, and a poor man in filthy old clothes also comes in.

John 13:3-5 (NIV) - Jesus Washes His Disciples’ Feet

3 Jesus knew that the Father had put all things under his power, and that he had come from God and was returning to God; 4 so he got up from the meal, took off his outer clothing, and wrapped a towel around his waist. 5 After that, he poured water into a basin and began to wash his disciples’ feet, drying them with the towel that was wrapped around him.

Luke 22:27 (NIV)

27 For who is greater, the one who is at the table or the one who serves? Is it not the one who is at the table? But I am among you as one who serves.

John 13:13-15 (NIV)

13 “You call me ‘Teacher’ and ‘Lord,’ and rightly so, for that is what I am. 14 Now that I, your Lord and Teacher, have washed your feet, you also should wash one another’s feet. 15 I have set you an example that you should do as I have done for you. 16 Very truly I tell you, no servant is greater than his master, nor is a messenger greater than the one who sent him. 17 Now that you know these things, you will be blessed if you do them.

Romans 12:16 (NIV)

16 Live in harmony with one another. Do not be proud, but be willing to associate with people of low position. Do not be conceited.
