"The desire to be God rather than to serve God lies at the bottom of every sin that anyone has ever committed. Sin isn't first rooted in a philosophical debate of the appropriateness or healthiness of a certain ethic. No, sin is rooted in my unwillingness to find joy in living my life under the authority of, and for the glory of, Another. Sin is rooted in my desire to live for me. It's driven by my propensity to indulge my every feeling, satisfy my every desire, and meet my every need."
--Paul David Tripp, Whiter than Snow: Meditations on Sin and Mercy
