Mark 12:30
Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength — the love command of Deuteronomy 6:5 is the first and greatest commandment. The four-fold all (heart, soul, mind, strength) communicates totality: the love of God is not one compartment of life alongside others but the comprehensive orientation of the whole person toward God. The heart (emotional center), soul (the self), mind (rational capacity), and strength (physical capacity) together constitute the complete human person.
