A.W. Tozer saw this when he wrote,
“What comes into our minds when we think about God is the most important thing about us. . . . The history of mankind will probably show that no people has ever risen above its religion, and man’s spiritual history will positively demonstrate that no religion has ever been greater than its idea of God. . . . Always the most revealing thing about the Church is her idea of God, just as her most significant message is what she says about Him or leaves unsaid, for her silence is often more eloquent than her speech. She can never escape the self-disclosure of her witness concerning God.”

Dietrich Bonhoeffer “Life Together”
“We must learn to know the Scriptures again, as the Reformers and our fathers knew them. We must know the Scriptures first and foremost for the sake of our salvation. But besides this, there are ample reasons that make this requirement exceedingly urgent. How, for example, shall we ever attain certainty and confidence in our personal and church activity if we do not stand on solid biblical ground? It is not our heart that determines our course, but God’s Word. But who in this day has any proper understanding of the need for scriptural proof? How often do we hear innumerable arguments ‘from life’ and ‘from experience’ put forward as the basis for the most crucial decisions but the argument of Scripture is missing. And this authority would perhaps point in exactly the opposite direction. It is not surprising, of course, that the person who attempts to cast discredit upon their wisdom should be the one who himself does not seriously read, know, and study the Scriptures. But one who will not learn to handle the Bible for himself is not an evangelical Christian.”
