I suppose the issue has been around for awhile. But, lately I've been contemplating sin and genetics. It seems that there is always new scientific research which leads to the conclusion that this or that various sin is genetic. (although, I have yet to see a scientist call it sin) From a worldly perspective, we look at this research and say, "Oh, that poor sinner, he can't help it, it must be okay for him to do it, then." This genetic research is one of the main reasons for popular acceptance of homosexual behavior.
However, if we apply the world's logic across the board, then we must accept murder as okay because psychopathic disorders are deemed genetic. So, perhaps we only accept genetics if the compulsion doesn't infringe upon the rights of other people which would leave out the psychopaths. In that case, is the genetic tendency toward addiction acceptable? Should we just give up upon alcoholics as a lost cause and allow them to give into their predisposition to become addicted to alcohol? Maybe we only allow it if they don't beat their families while in a drunken rage. No. Sin is sin.
I believe that because of this mainstream acceptance, many Christians have had a knee-jerk reaction loudly proclaiming that homosexuality is not genetic. I am far from being an expert, but I question that knee-jerking. Personally, I don't have a problem with the research that concludes that these sins may be genetic. I reason that the Fall was complete and total. For sin to seep to the genetic level is not unfathomable to me. In fact, I suppose that if they did a research study to discover whether the sin of pride were genetic, they could easily nail me as a genetically prideful person. Just because I am (supposedly) predisposed to this particular sin, does not make it okay for me to disobey the word of God. It only means that one person will struggle more intensely with a particular sin than other people will. I have always believed that each of us has certain sins which we struggle with more than others. "Shall the thing formed say to him who has made it, "why hast thou made me thus?" No.
Our constant struggle with sin is only a daily reminder of our need for a Savior. If we say that sin is okay, then we lose that need. If we lose that need, then all is lost indeed.
