Intrinsic motivation refers to engaging in an activity for its inherent meaning, enjoyment, or sense of calling, whereas extrinsic motivation involves acting to gain external rewards or avoid punishment, a distinction rigorously developed in psychology by Harry Harlow (1950) and later formalized by Edward L. Deci and Richard M. Ryan through Self-Determination Theory (Deci, 1971; Deci & Ryan, 1985, 2000), with earlier organisational insights also reflected in Herzberg’s motivation–hygiene theory (Herzberg et al., 1959). From a Christian perspective, intrinsic motivation resonates with the Biblical call to act from the heart and in faithfulness to God: “Whatever you do, work at it with all your heart, as working for the Lord” (Colossians 3:23, KJV). Extrinsic motivation parallels Jesus’ caution against acting merely for public reward (Matthew 6:1–4), reminding believers that God “weighs the motives” (Proverbs 16:2). When people are guided primarily by intrinsic motives such as purpose, service, and love of truth rather than by status or reward alone (Galatians 1:10), research shows greater wellbeing, persistence, and ethical behaviour, benefits that extend beyond the individual to healthier families, workplaces, and societies, where citizens act not only because they must, but because they believe it is good and right to do so.
