From early instinct theories in the 1900s to contemporary models of self-determination, the study of motivation in psychology has sought to explain why humans act, persist, and thrive.

William James (1890) and later Sigmund Freud (1915) framed motivation in terms of innate drives, which gave way to behaviourist explanations, most famous of which is B. F. Skinner’s work in the 1930s–1950s showing how reinforcement shapes action. A major shift came with the humanistic movement, where Abraham Maslow (1943) proposed the Hierarchy of Needs, arguing that people are driven not only by survival but by growth and meaning. In the late twentieth century, Edward Deci and Richard Ryan’s Self-Determination Theory (1985) offered a landmark view that autonomy, competence, and relatedness energise healthy motivation. These studies have deeply influenced approaches to personal wellbeing, helping individuals cultivate intrinsic purpose and resilience, and have informed societal health by shaping education, workplace policy, and community design around the conditions that help people flourish.

The history of motivation studies in psychology can be viewed from a Christian perspective as humanity’s ongoing attempt to understand the deeper forces that move human behaviour, desire, and purpose, themes that Scripture has long addressed through theological reflection on the human heart and soul. Prior to all motivation research, Christian scripture provided a clear picture of the most fundamental human motivation – the deepest hunger and thirst of the soul (e.g. Isaiah 55; Matthew 5:6; Psalm 143:6; John 4:14, 6:35, 7:37; Psalm 42:2; Psalm 63:1; Psalm 107:9; Revelation 7:16-17).

Christianity affirms that psychological theories capture partial truths about human nature yet argues that authentic motivation cannot be fully understood apart from humanity’s relationship with God, The reason for this is that “the heart is deceitful above all things” (Jeremiah 17:9) and human beings are ultimately created to glorify God and love others (Matthew 22:37–39). Augustine of Hippo famously wrote, “You have made us for yourself, O Lord, and our heart is restless until it rests in you” (Confessions, I.1), expressing the theological belief that human desires and motivations find their true fulfilment only in God.

Christian thinkers therefore critique purely reductionist or secular accounts of motivation for neglecting spiritual dimensions such as sin, grace, vocation, and transformation through the Holy Spirit, while also appreciating modern psychological insights into needs, cognition, and social behaviour as reflections of God’s common grace. Contemporary Christian psychology often integrates motivational theories such as self-determination theory with Biblical concepts of stewardship, calling, and sanctification, emphasising that human motivation is most healthy when oriented toward love, service, and communion with God, as reflected in Philippians 2:13: “for it is God who works in you to will and to act in order to fulfil his good purpose.”
