We must make a great difference between God’s Word and the word of man. A man’s word is a little sound which flieth into the air, and soon vanisheth; but the Word of God is greater than Heaven and earth, yea, it is greater than death and hell, for it is the power of God, and remaineth everlastingly. Therefore we ought diligently to learn God’s Word, and we must know certainly and believe that God Himself speaketh with us.
— Martin Luther (1483-1546)
