Chemistry, Genes and Moral Judgement

Q: Do physical chemistry and genes affect our moral judgments? How can God hold us accountable for obedience and accountability when some individuals are apparently not in control of their feelings and actions? Isn't it easier to behave better some days than others?

A: Quite honestly, that question has troubled me until recently. The hyperactive child, for example, is often more rebellious than the boy or girl who is calm. How will his defiant nature affect his future relationship with God? What about the sexual deviate who was warped by emotional turmoil during his/her formative years? What exceptions does God make for the person whose parents taught him immoral concepts at home? How about the woman who abuses others during premenstrual tension? What about the person who is possibly driven by chemicals we don't even fully comprehend medically and are the subject of controversial disagreements even among experts?
These issues defy human interpretation, although they no longer distress me from a theological point of view. An infinite God who rules the vast universe is capable of judging those exceptions or individuals in a way that will be infinitely just. It is not my business to decipher God's system of evaluation. His ways are higher than my ways, and His thoughts are higher than my thoughts. Isn't that why the Bible commands us not to judge one another? We are obviously not equipped to handle that assignment. All I know is that the Lord has required trust and obedience of me. As to the reactions of fellowmen I hear Him saying, "What is that to thee? You follow me."
