Book excerpt: Our intellectual context is very complicated. There are competing pedagogues, divergent epistemological agendas, and flawed participants. The mind is a warzone. The Old Testament depicts a battlefield between the sinful mind and God's revelation. Today, many Christians minimize the intellect and do not recognize how sin impacts thinking. Many do not know how to love God with the mind. Many suffer from anti-intellectual inertia. They think like consumers shopping for knowledge, learning formats, and instructors that conform to their buying preferences. They prefer junk food for their minds. They often fulfill the role assigned to them by the world--intellectual simplicity, private religiosity, and subjective spirituality. By comprehensively examining Old Testament teaching concerning the mind, this book promotes a spirituality that puts thinking in its proper place. It explains what God requires intellectually of his vice-regents. It shows that our world is a labyrinth, but that God's revelation is our reliable guide. This book motivates readers to strive for mental piety, wisdom, and intellectual development, for the glory of God and the fulfillment of our mandate on earth. Readers will learn from their ancient brethren how to better steward their minds.
