As Dr. Martyn Lloyd-Jones says in his exposition of Romans 6, though sin cannot reign in us, that is, in our essential personality, it can, if left unchecked, reign in our mortal bodies.[4] It will turn the natural instincts of our bodies into lust. It will turn our natural appetites into indulgence, our need for clothing and shelter into materialism, and our normal sexual interest into immorality.
