The study of motivation is best understood within a fully integrative model of psychology that recognises the human person as a dynamic unity of at least eight interrelated dimensions—core, spiritual, cognitive, motivational, emotional, physical, behavioural, and contextual—because motivation never emerges in isolation but is shaped continuously by beliefs, values, emotions, bodily states, relationships, culture, and ultimate meaning.
Accordingly, a number of major scholars have argued for a genuinely comprehensive psychology that includes spirituality as an essential component of human functioning, including William James (1902), Gordon Allport (1950), Viktor Frankl (1963), Abraham Maslow (1968), Kenneth Pargament (1997), George Engel (1977), whose biopsychosocial model opened the way for broader multidimensional approaches, and Martin Seligman (2011), whose positive psychology increasingly acknowledged meaning, transcendence, and virtue.
From a Christian perspective, such a framework is especially necessary because Scripture portrays human beings holistically as embodied, relational, moral, and spiritual creatures made in the image of God (Genesis 1:26–27), called to love God with heart, soul, mind, and strength (Mark 12:30), renewed through transformation of the mind (Romans 12:2), sustained spiritually as well as physically (Matthew 4:4), and formed within communities that shape conduct and identity (Hebrews 10:24–25).
Christian theology historically affirms the integration of body, soul, reason, desire, virtue, and social life in the flourishing of the person, as seen in the writings of Augustine of Hippo and Thomas Aquinas. Consequently, an eight-dimensional model provides a richer and more accurate foundation for understanding motivation, fostering personal wellbeing through integrated growth, resilience, moral formation, meaning, and healthy relationships, while also contributing to societal health by encouraging compassion, ethical responsibility, social cohesion, psychological maturity, and a deeper recognition of the dignity and interconnectedness of every human person.
