Commands of Jesus:
Be humble!

But you are not to be called ‘Rabbi,’ for you have one Teacher, and you are all brothers. And do not call anyone on earth your father, for you have one Father, who is in heaven. Nor are you to be called instructors, for you have one Instructor, the Christ. The greatest among you shall be your servant. For whoever exalts himself will be humbled, and whoever humbles himself will be exalted. Matthew 23:8-12

Therefore, whoever humbles himself like this little child is the greatest in the kingdom of heaven. Matthew 18:4

Now people were bringing the little children to Jesus for Him to place His hands on them, and the disciples rebuked those who brought them. But when Jesus saw this, He was indignant and told them, “Let the little children come to Me, and do not hinder them! For the kingdom of God belongs to such as these. Truly I tell you, anyone who does not receive the kingdom of God like a little child will never enter it.”And He took the children in His arms, placed His hands on them, and blessed them. Mark 10:13-16

A dispute also arose among the disciples as to which of them would be considered the greatest. So Jesus declared, “The kings of the Gentiles lord it over them, and those in authority over them call themselves benefactors. But you shall not be like them. Instead, the greatest among you should be like the youngest, and the one who leads like the one who serves. For who is greater, the one who reclines at the table or the one who serves? Is it not the one who reclines? But I am among you as one who serves. Luke 22:24-27
