One thing for sure in becoming a "fan" of football is learning how important the word "fair" becomes. You never want to come to the end of that final few minutes of the game and feel as though you could have won if the other team hadn't had an unfair advantage (whatever that may be). I'm not naive enough to believe that all is fair in the very physical game of football, but I like to believe that my team always has a "fair" shot at winning.
Now lets' take the focus away from football and look at how fairness plays out in families. Do you remember when you were a child and things didn't go the way you wanted - these words came out of your mouth, "That's not fair!" In your little world at that very moment, you thought everyone was against you and partiality was being shown to the person on the opposite side. Of course, most of this was in your mind because your feelings were hurt, but nonetheless very real at the moment.
I dare say now that you are a parent yourself, you've heard your own children say that phrase and think you like their sibling more than them. Go back to that moment in time and remember how you felt when you thought you were being treated unfairly. How you react to your little one will be remembered. Depending on your child's age...this could be a great time for a lesson on how there are times when it seems life isn't fair, but they are responsible in how they react in these situations. Let them know that you understand how they feel, because as a child you felt that way at times too. Just keep in mind as you teach this, they know you love them and you are always "on their side" as your child...but not always in agreement with what they do. Help them to see how important it is to treat others fairly, because that is what they want for themselves.
The scripture in Matthew 7:12 sums it up. " So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets." Treat others with fairness because it is the right thing to do and because that is the way you would want to be treated.
