Our critical faculties are given us for the purpose of self-examination, and the way to examine ourselves under the control of the Spirit of God is to ask ourselves—"Am I less sensitive than I used to be to the indications of God's will, less sensitive regarding purity, uprightness, goodness, honesty and truth?" If I realise that I am, I may be perfectly certain that something I have done (not something done to me) has seared my conscience. It has given me, so to speak, a bloodshot eye of the soul and I cannot see aright.
