I was born with a short temper.
I was born with an appreciation for sports.
I was born with a tendency to overeat.
I was born with a love for nature and the great outdoors.
I was born with sexual attractions for women besides my wife.
I was born with a love for excessive TV watching.
I was born with a love for knowledge acquisition, preferably through reading.
I was born with a desire to be in control and to overpower people.
I was born with a penchant toward sarcasm and cruelty.
Which of these natural tenancies should I develop? Which should I restrain? Which are morally and socially beneficial?
Being born a certain way in no way determines its goodness, so I've decided to turn to Holy Scripture and to be guided by its teachings, as revealed and fulfilled through Jesus Christ (see this post for those who wonder how Christians determine which laws from the Old Testament are still in play).
Beware of arguments that suggest "how I feel" means "how I should act." Moral philosophers call this creating "ought" where there is only "is." Morality stands outside of nature (supernatural). Any morality that shifts with culture ends up not being morality at all because it's been relegated to a natural entity. But when I allow an outside morality to serve as the standard of moral actions and behaviors, it is certain that I will fall short, experience shame, and feel guilt.
Turns out, contrary to modern ears, shame and guilt are exactly how you should feel when you go against morality. Shame and guilt are gifts, designed to send us toward healing, hope, and forgiveness. And where can we turn to feel this way, to know this forgiveness? Only Jesus. He identified with those most shamed and most guilty in his day (prostitutes, criminals, sexual deviants). He loved them; extended them forgiveness; invited them to repentance; and said that surely the kingdom of God is for such as these. And so I come with all my deviant natural tendencies...O Lord, receive me again, through your cleansing and sacrificial blood.
