from John Piper, God’s Passion for His Glory: Living the Vision of Jonathan Edwards. Wheaton: Crossway, 1998.
Edwards has taught me…that our concern with truth is an inevitable expression of our concern with God. If God exists, then he is the measure of all things, and what he thinks about all things is the measure of what we should think. Not to care about the truth is not to care about God. To love God passionately is to love truth passionately. Being God-centered in life means being truth-driven in ministry. What is not true is not of God. What is false is anti-God. Indifference to the truth is indifference to the mind of God.
Our concern with truth is simply an echo of our concern with God. And all this is rooted in God’s concern with God, or God’s passion for the glory of God.
