Influenced vs. Determined

Most researchers are quick to point out that the biologically oriented studies suggest that genetics can influence people, and with this scripture has no dispute. People can be physiologically predisposed to enjoying a particular drug, food, activity, or physical experience, but there is a categorical difference between being influenced by genetics and being determined by it. Possible physiological tendencies do not mean that self-control is impossible or that personal responsibility is diminished. They simply mean that some people must be more vigilant in situations where that sin can be easily provoked.
