When the Heart Lights Go On - A.W.Tozer
God is concerned with the whole man and has designed that Christian experience should embrace the entire personality. The Christian faith deals not with the spiritual only but with the moral and the rational as well. The rational and moral elements in religion are the proper objects of thought and willingly yield their rich treasures to prayerful meditation. The Christian faith deals with God and man and what can be known about them and their relation one to the other. It contemplates creation, redemption, righteousness, sacred history, the destiny of mankind and the future of the world. Such truths, once they have been revealed by divine inspiration, lie where they can be got at by the redeemed intellect and wait to be exploited by the sons of the kingdom. Under the illumination and guidance of the Holy Spirit the prayerful, studious believer can become a Christian philosopher, a sage, a doctor of divine things. More than that, he can become a man of God and a light to his generation. I repeat, we cannot know God by thinking alone, but we can never know Him very well without a lot of hard thinking.
