There isn't any ranking or class in the kingdom.
35 He sat down, called the twelve disciples over to Him, and said, "Whoever wants to be first must take last place and be the servant of everyone else." 36 Then He put a little child among them. Taking the child in His arms, He said to them, 37 "Anyone who welcomes a little child like this on My behalf welcomes Me, and anyone who welcomes Me welcomes not only Me but also My Father who sent Me." 38 John said to Jesus, "Teacher, we saw someone using Your name to cast out demons, but we told him to stop because he wasn't in our group." 39 "Don't stop him!" Jesus said. "No one who performs a miracle in My name will soon be able to speak evil of Me. 40 Anyone who is not against us is for us. 41 If anyone gives you even a cup of water because you belong to the Messiah, I tell you the truth, that person will surely be rewarded.
Ever since the beginning of time people have had a difficult time with status. Adam and Eve tried to be like God, Cain didn't want Abel to be better at giving offerings, Lot chose to have the best real estate for his own and left Abram with the leftovers.
Even Jesus disciples struggled with the concept of looking at themselves and others without placing a ranking on them. They argued about which one of the twelve was number one and they probably thought that they out classed the people around them because they were the chosen ones. Those guys even stopped a "competitor" that was doing kingdom work just because he wasn't one of them.
I need to work for Jesus without any concern for how great my ministry may be or how popular it is. Jesus said that even if I just pass out water to help those that are spreading the gospel then I am doing work that is worthy of being rewarded.
Help me to always be ready to serve, no matter how lowly the job may seem to be, I want to walk humbly and with meekness so that you are glorified through my good works.
