“Beware of any work for God that causes or allows you to avoid concentrating on Him. A great number of Christian workers worship their work. The only concern of Christian workers should be their concentration on God. This will mean that all the other boundaries of life, whether they are mental, moral, or spiritual limits, are completely free with the freedom God gives His child; that is, a worshiping child, not a wayward one. A worker who lacks this serious controlling emphasis of concentration on God is apt to become overly burdened by his work. He is a slave to his own limits, having no freedom of his body, mind, or spirit. Consequently, he becomes burned out and defeated. There is no freedom and no delight in life at all. His nerves, mind, and heart are so overwhelmed that God’s blessing cannot rest on him.”
― Oswald Chambers, My Utmost for His Highest

“So live as if you were living already for the second time and as if you had acted the first time as wrongly as you are about to act now!”
― Viktor E. Frankl, Man's Search for Meaning

“It is safe to tell the pure in heart that they shall see God, for only the pure in heart want to.”
― C.S. Lewis, The Problem of Pain

“And out of that hopeless attempt has come nearly all that we call human history—money, poverty, ambition, war, prostitution, classes, empires, slavery—the long terrible story of man trying to find something other than God which will make him happy.”
― C.S. Lewis, Mere Christianity
