Soteriology is the study of salvation. The word soteriology is derived from the Greek words "soter" (σωτήρ), which means savior, and "logos" (λόγος), which means a word about, or the study of something. Soteriology is the sphere of systematic theology that speaks to the nature, means, scope, and purpose of salvation. It is an important theme that runs throughout Scripture and reveals the God who saves.
