Me first! Me first! Do you ever hear these words? I suppose competition (maybe the better word is selfishness) among kids is inevitable considering their sinful nature. Having three children, close in age, I used to hear these words a lot. So, I had a talk with them and taught them the scripture that says "the last shall be first, and the first last..." Matt. 16:20. I told them that whoever yelled out "Me first!" was automatically going to be last to get whatever they were wanting. Well, after putting this into practice and them realizing what was going to happen if they asked to be first, it started a new practice. Instead of saying "me first", they started saying "Me last! Me last!".
Okay, maybe I didn't really solve my immediate dilemma, but hopefully the principal from scripture was drilled in their head enough that they will never forget it.
