"There is within the human heart a tough fibrous root of fallen life whose nature is to possess, always to possess. It covets "things" with a deep and fierce passion...The roots of our hearts have grown down into things, and we dare not pull up one rootlet lest we die. Things have become necessary to us, a development never originally intended. God's gifts now take the place of God, and the whole course of nature is upset by the monstrous substitution."
A.W. Tozer, The Pursuit of God
