In this article, it is inquired which reasons are decisive for acting in accordance with divine commands, and whether these can be regarded as moral reasons; the emphasis lies on Christianity. To this effect, the position of God as a—basic—lawgiver is expounded, with special attention to the role His power plays. By means of an account of the grounds given (in the Bible) to obey God, the selfish motives in this respect are brought to light. It is questioned whether any other elements can be discerned, particularly from a meta-ethical perspective.
