He proposes that God's commands precede moral truths and must be explained in terms of moral truths, not the other way around. Adams writes that his theory is an attempt to define what being ethically 'wrong' consists of and accepts that it is only useful to those within a Judeo-Christian context. In dealing with the criticism that a seemingly immoral act would be obligatory if God commanded it, he proposes that God does not command cruelty for its own sake. Adams does not propose that it would be logically impossible for God to command cruelty, rather that it would be unthinkable for him to do so because of his nature. Adams emphasises the importance of faith in God, specifically faith in God's goodness, as well as his existence.
