" Thinking is indispensable on the path to passion for God. Thinking is not an end in itself. Nothing but God himself is finally an end in itself. Thinking is not the goal of life. Thinking can be the ground for boasting. Thinking, without prayer, without the Holy Spirit, without obedience, without love, will puff up and destroy (1 Cor. 8:1).

But thinking under the mighty hand of God, thinking soaked in prayer, thinking carried by the Holy Spirit, thinking tethered to the Bible, thinking in pursuit of more reasons to praise and proclaim the glories of God, thinking in the service of love--such thinking is indispensable in a life of fullest praise to God. "
