It is idle to talk always of the alternative of reason or faith.
Reason is itself a matter of faith. It is an act of faith to assert that out thoughts have any relation to reality at all. If you are merely a skeptic, you must sooner or later ask yourself the question, “Why should anything go right; even observation and deduction?” Why should not good logic be as misleading as bad logic? – G. K. Chesterton, Orthodoxy
Reason and faith may, at times, produce conflict between the two but ultimately the work hand in hand. Shallow reasoning may fail to resolve the conflict but that is not the fault of reason or faith.
Reason without faith fails miserably and faith in faith without reason not only crumbles at the most inconvenient of timing but often hurts others in the process. The God who gave us the ability to exercise both calls upon each one of us, individually and then corporately, to humble ourselves and not only cease to do that which He calls evil but learn to do well.
Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. Holy Bible Isaiah 1:18
