I was listening to a podcast by about the fairness of Christianity. He contended that Christianity is not based on fairness, but truth. It does not seem fair that one sin would make us a sinner, but that is indeed the case. When disobeyed God, we inherited their punishment, and all became sinners in need of grace; the issue of fairness went out the window. We are all sinners, because not one person can say they have not sinned; one sin makes a sinner. And because of God's justice, sin has to be accounted for.
Yesterday I got an application for life insurance from AAA. One of the questions was have you used nicotine in the last twelve months. It seemed unfair, and totally legalistic. Have just one cigarette in a year's time and you're paying more than twice the normal rate. Does one cigarette a year make one a smoker? I personally don't think so. At the same time, there's no gray area: if you've smoked once, you're a smoker, as far as AAA is concerned. Doesn't seem fair. In any case, I made a resolve not to smoke at all for the next year, so that, if anything, I can answer the question of nicotine use honestly and receive a lower rate.
I can resolve to not smoke and follow through on that and free myself from the higher rates for life insurance, but the same cannot be said about my sin. I cannot free myself from damnation by resolving never to sin again, because it would never work. No matter how hard I try to get myself into the 'no sin' category, I would fall short, guaranteed.
I don't believe that one cigarette a year makes one a bonafide smoker; but the least sin, no matter how small, makes us fall short of the perfection that God demands, and as such, makes us unworthy of heaven. Christ bore the punishment for our sins. The way to salvation is through faith in him, through the faith that trusts that God accepted Christ's perfect sacrifice for us as sufficient to merit heaven. Doesn't seem very fair to me that Christ should have to die. But then again, just because it's not fair doesn't mean its not true.
