A few years ago, scientists claimed to have discovered the “adultery gene,” showing that certain people have a genetic predisposition to unfaithfulness. Other scientists have made similar claims about homosexuality, alcoholism, addictions, physically abusive behavior, etc. Could it be that certain people are led by their natures to certain sins? Why not? That neither relieves them of responsibility nor makes sin inevitable.
The Bible makes it clear that our natural tendencies, when left unchecked, lead us to sin. The use of the Greek word “sarx” in the New Testament illustrates this concept. The flesh goes against the Spirit. You cannot follow the flesh and please God. Passages like Romans 8 and Galatians 5 make this exceedingly clear.
We aren’t hard-wired for holiness. We need the help of the Spirit of God to achieve that. Following what is natural will not lead us to God. Proving that something is “just natural” is a good way to prove that it probably isn’t godly. We have to overcome what is natural, become supernatural, become spiritual beings. Natural just won’t cut it.
