Warning: This may touch a nerve...
3 "For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith. 4 For as we have many members in one body, but all the members do not have the same function, 5 so we, being many, are one body in Christ, and individually members of one another."
Again remember the context - Jews and Gentiles under one roof having Jesus in common.
Several years ago I had a situation where the church I was pastoring was having some special evening meetings but I was not the speaker. At the same time we were trying to get to reach out to the people who were clients of our food bank and the surrounding neighbourhood. There was one evening when the activities at the two locations overlapped and I chose to go to the food bank first and when that was finished and I went over to the church. I had barely come in the church door when I was confronted by a less than happy church member who felt I should have been at the church all evening. I will never forget their words: "Aren't we more important than them?"
I'm quite certain the look of shock on my face made an answer to the question unnecessary.
Pride is an evil thing and it can enter our thinking so subtly. We associate material superiority with self importance. Really? Abraham Lincoln was raised in poverty. So were countless others who went on to have a huge impact on our world.
The Jews had a superiority complex because God chose them. God gave them the tablets of stone and the sanctuary and the prophets and the priesthood and the Messiah so you better understand lowly Gentile that you are a second class Christian... tragic and worse ignorant.
You see if the Jews were honest with their family tree they would be forced to conclude that it contained a lot of Gentiles right in the direct line that lead to Jesus. Not only were there lots of Gentiles but lots of humiliating scandal too.
Acts 17:26 says "He has made from one blood all nations of men".
It was the belief in superiority of some over others that motivated Hitler and other historical "monsters".
Read today's verses again. We may be different in looks, wealth, abilities, etc... but none are better than or have more value. Next time you are tempted to look down at someone remember that - all nations: one blood.
