And you shall love the LORD your God with all your heart, and with all your soul, and with all your might.
All Commentaries on Deuteronomy 6:5 Go To Deuteronomy 6
Augustine of Hippo
AD 430
Therefore the supreme and true wisdom is in that first commandment: “You shall love the Lord your God with your whole heart and with your whole soul.” From this it follows that wisdom is love of God, which is “poured forth in our hearts,” not otherwise than “by the Holy Spirit who is given to us.” But “the fear of the Lord is the beginning of wisdom,” and “there is no fear in love, but perfect love casts out fear.”
