It may also be helpful to look at another blog I've written ...to give perspective on things that in some sense we may think are not fair, but which happen all the time & most often without us questioning the fairness of it.

If you look at the example of the basketball coach, you may view the starting five as the five most talented players on the team. Unless you feel your kid is better than the coach's kid ...and even then you may somewhat understand that under the same circumstances, if you were the coach you may start your kid even if another player is better.

But, when viewing God ...we don't perceive Him to be judging us on talent, nor any other standard of preference.  We may feel it's like free play on a playground ...where everyone gets to participate.

Or we view it as some special experience we have with God ...like going to an amusement park, and we all get to ride as many rides as we want.  We also get as many treats as we want.  And when the day is done, we are promised we can do the same tomorrow.

Well, God gives us many wonderful promises ...but life is not exclusively like an amusement park, unless you are just generally using the analogy of the roller coaster with its ups & downs.

We do mostly agree that God is fair ...except for those who may be arguing our understanding or beliefs, and questioning whether God is who we say He is, or whether He exists at all.

So, if we do agree that God is fair, do we also believe that He would decide to give consequences to us for other people's behavior??  It is my experience that people readily have difficulty accepting this as within the realm of God's fairness ...yet, for basketball and other sports it is common that the whole team suffer extra workouts for one person's mess ups.

If we read in the Bible that all sin came through Adam ...we may accept that as fair in the same way that we would understand it if we had an Adam in our neighborhood who was a reckless driver who almost killed a school child, and as a result of that the community reduces the speed limit in the school zone and increases the fine for speeding.  We could say that the speed limit came about through Adam, and not have difficulty understanding the necessity of it.

Yet, if a missionary tells an islander who has been isolated from any contact with the outside world that their sin and punishment for all their sin came through Adam ...the islander may not know you from Adam, yet may feel some emotion which isn't on the favorable end of the continuum. That sort of misunderstanding could elicit a feeling close to hate for Adam, and possibly for you too.

On the other hand, if the islander was told that all people sin, and God gave Adam a chance to have everything 'good' ---but, Adam messed up ---then it would be easier to accept, and the islander may even relate to and feel a bit sorry for Adam.

And the island may even be filled with thrill and excitement if they were told that another person was provided the opportunity to succeed where Adam and all others have failed ...especially when told the Person did succeed, and as a result the ultimate punishment did not have to come.
