Christianity is Reasonable

Lloyd-Jones Eph 6,11

We are to put on the whole armour of God—for, or because, ‘we wrestle not’ etc. This is one of the most glorious aspects of the Christian faith. You cannot reason yourself into it, but the moment you are in it you find that it is the most reasonable thing in the world, full of understanding, full of explanations. Christianity, unlike so many of the cults, is not merely something which teaches you to persuade yourself in a thoughtless manner. It does not just tell you to say something, and to go on saying it mechanically, whether it be true or not, and whether you feel it or not. That is not Christianity. It always gives reasons.”

Ultimate Presuppositions

“But herein precisely lies the fundamental point of difference between Romanism (Roman Catholicism) and Protestantism. According to the principle of Protestantism, man’s consciousness of self and of objects presuppose for their intelligibility the self-consciousness of God. In asserting this we are not thinking of psychological and temporal priority. We are thinking only of the question as to what is the final reference point in interpretation. The Protestant principle finds this in the self-contained ontological trinity. By his counsel the triune God controls whatsoever comes to pass. If then the human consciousness must, in the nature of the case, always be the proximate starting-point, it remains true that God is always the most basic and therefore the ultimate or final reference point in human interpretation.
This is, in the last analysis, the question as to what are one’s ultimate presuppositions. When man became a sinner he made of himself instead of God the ultimate or final reference point. And it is precisely this presupposition, as it controls without exception all forms of non-Christian philosophy, that must be brought into question. If this presupposition is left unquestioned in any field all the facts and arguments presented to the unbeliever will be made over by him according to his pattern. The sinner has cemented colored glasses to his eyes which he cannot remove. And all is yellow to the jaundiced eye. There can be no intelligible reasoning unless those who reason together understand what they mean by their words.”
