This article aims to provide an a priori argument-termed the Flourishment Argument, for the veracity of the Christian conception of the Abrahamic religion that centres on God's action of sending a divine and atoning prophet into the world. This specific informal argument will be presented through the formulation of a set of a priori reasons for why God would seek to interact with the world-developed in light of the work of Richard Swinburne, John Finnis, Linda Zagzebski and Alexander Pruss-which, in combination, will provide individuals with grounds for believing in the veracity of these important Christian teachings.
