Ultimately, however, conflict lies not in objective reality, but in people's heads. Truth is simple one argument - perhaps a good one, perhaps not - for dealing with the difference. The difference itself exists because it exists in their thinking.
Martin LutherWhen the devil wants to cause offense against the true doctrine and faith, he does not do so through insignificant people, who do not rate highly with the world, but through those who are the very best, the wisest, the holiest, and the most learned.
Martin LutherDoes it follow from: 'turn ye' that therefore you can turn? Does it follow from "'Love the Lord thy God with all thy heart' (Deut 6.5) that therefore you can love with all your heart? What do arguments of this kind prove, but the 'free-will' does not need the grace of God, but can do all things by its own power....But it does not follow from this that man is converted by his own power, nor do the words say so; they simply say: "if thou wilt turn,telling man what he should do. When he knows it, and sees that he cannot do it, he will ask whence he may find ability to do it..." 164
