(Proverbs 22:2 KJV) The rich and poor meet together: the LORD is the maker of them all.
Friendship involves going through common experiences. When you cease to share you can drift apart. Often it is the struggles which build the strongest bonds. Too often social barriers keep those bonds from happening. I remember when my parents forced us to change churches when I was a kid. I hated the change but it was a very healthy one for all of us. We left a church of people like us socially and went to one that had people “above” us. I never knew it.
The church we went to had judges and millionaires who treated my blue-collar father like the honorable man he was. Although he worked with his hands and only graduated from high school, he was accepted and never felt out of place. That is the way the church should be.
So? How do you get along with the janitor where you work? You are the janitor? How do you get along with the people you clean up after? If you are brothers in Christ you should have a bond. Even if you don’t, Christian courtesy is the order of the day.
