Bill Hybels quote: “God is righteous and just, holy and tender, responsive and sympathetic. He is willing--anxious even--to hear from you. …”

“Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?”

Epicurus (-341–-269 BC) ancient Greek philosopher

This attribution occurs in chapter 13 (Ioan. Graphei, 1532, p. 494) http://books.google.com/books?id=rs47AAAAcAAJ&pg=PA494 of the Christian church father's Lactantius's De Ira Dei (c. 318):
"God," he [Epicurus] says, "either wants to eliminate bad things and cannot,
or can but does not want to,
or neither wishes to nor can,
or both wants to and can.
If he wants to and cannot, then he is weak and this does not apply to god.
If he can but does not want to, then he is spiteful which is equally foreign to god's nature.
If he neither wants to nor can, he is both weak and spiteful, and so not a god.
If he wants to and can, which is the only thing fitting for a god, where then do bad things come from? Or why does he not eliminate them?"
Lactantius, On the Anger of God, 13.19
Charles Bray, in his 1863 The Philosophy of Necessity: Or, Natural Law as Applicable to Moral, Mental, and Social Science quotes Epicurus without citation as saying a variant of the above statement (p. 41) http://books.google.com/books?id=BebVAAAAMAAJ&pg=PA41 (with "is not omnipotent" for "is impotent"). This quote appeared in "On the proofs of the existence of God: a lecture and answer questions" http://www.atheism.ru/old/KryAth2.html (1960) by professor Kryvelev I.A. (Крывелёв И.А. О доказательствах бытия божия: лекция и ответы на вопросы. М., 1960). And N. A. Nicholson, in his 1864 Philosophical Papers (p. 40), attributes "the famous questions" to Epicurus, using the wording used earlier by Hume (with "is he" for "he is") http://books.google.com/books?id=ZMsGAAAAcAAJ&pg=PA40. Hume's statement occurs in Book X (p. 186) http://books.google.com/books?id=E7dbAAAAQAAJ&pg=PA186 of his renowned Dialogues Concerning Natural Religion, published posthumously in 1779. The character Philo precedes the statement with "Epicurus's old questions are yet unanswered.…". Hume is following the enormously influential Dictionnaire Historique et Critique (1697–1702) of Pierre Bayle, which quotes Lactantius attributing the questions to Epicurus (Desoer, 1820, p. 479) http://books.google.com/books?id=QwwZAAAAYAAJ&pg=PA479.
There has also arisen a further disputed extension, for which there has been found no published source prior to The Heretic's Handbook of Quotations: Cutting Comments on Burning Issues (1992) by Charles Bufe, p. 186: "Is he neither able nor willing? Then why call him God?"

“He wills that some things shall be contingent and others necessary, but he wills in the same act that the contingency shall be necessary.”

Henry Adams (1838–1918) journalist, historian, academic, novelist

Mont Saint Michel and Chartres (1904)
Context: Creation was not successive; it was one instantaneous thought and act, identical with the will, and was complete and unchangeabble from end to end, including time as one of its functions. Thomas was as clear as possible on that point:— "Supposing God wills anything in effect, he cannot will not to will it, because his will cannot change." He wills that some things shall be contingent and others necessary, but he wills in the same act that the contingency shall be necessary. "They are contingent because God has willed them to be so, and with this object has subjected them to causes which are so." In the same way he wills that his creation shall develop itself in time and space and sequence, but he creates these conditions as well as the events. He creates the whole, in one act, complete, unchangeable, and it is then unfolded like a rolling panorama with its predetermined contingencies.Man's free choice — liberum arbitrium — falls easily into place as a predetermined contingency. God is the First Cause, and acts in all Secondary Causes directly; but while he acts mechanically on the rest of creation,— as far as is known,— he acts freely at one point, and this free action remains free as far as it extends on that line. Man's freedom derives from this source, but it is simply apparent, as far as he is a cause; it is a [... ] Reflex Action of the complicated mirror [... ] called Mind, and [... ] an illusion arising from the extreme delicacy of the machine.

“The man who abides in the will of God wills nothing else than what God is, and what He wills.”

Meister Eckhart (1260–1328) German theologian

Meister Eckhart’s Sermons (1909)
Context: The man who abides in the will of God wills nothing else than what God is, and what He wills. If he were ill he would not wish to be well. If he really abides in God's will, all pain is to him a joy, all complication, simple: yea, even the pains of hell would be a joy to him. He is free and gone out from himself, and from all that he receives, he must be free. If my eye is to discern colour, it must itself be free from all colour. The eye with which I see God is the same with which God sees me. My eye and God's eye is one eye, and one sight, and one knowledge, and one love.

“God's calling requires action. When God calls you, he calls collect … you better be willing to accept the charges of your calling.”

“God will transplant the root, if he wills to rear it into fruit-bearing.”

Margaret Fuller (1810–1850) American feminist, poet, author, and activist

Letter (Spring 1850).
Memoirs of Margaret Fuller Ossoli (1852)
Context: I feel perfectly willing to stay my threescore years and ten, if it be thought I need so much tuition from this planet; but it seems to me that my future upon earth will soon close. It may be terribly trying, but it will not be so very long, now. God will transplant the root, if he wills to rear it into fruit-bearing.
