When mortal mind "goes to doubting" the power of good, we need not assume the onus, and thus unwittingly give our sanction to its claim to be within us. To do so is to identify ourselves with the attitude and habit of this mortal mind; whereas, if the message of the Christ be true, we should and do reflect immortal Mind, and therein alone is man's identity discovered and maintained.
Rejecting, then, the doubt, as no proper part of our mentality, because it is no part of God or His manifestation, we can trust good in spite of doubt, and to an ever-increasing realization and achievement. Fidelity in this direction must have its reward in the destruction of the doubting tendency, a mark of approximation to that Mind which knows no doubt because it knows no error.
Things which are not good things are no things. The teachings of the Christ, as explained and made practical through Christian Science, make this incontrovertibly clear. Evil things are but misconceived and distorted mental images of primarily good things. We need not succumb to doubts as to the ever presence and potential demonstrability of good. Such fears are of those "vain imaginations" of which the Scriptures speak, and they are occasioned by our human ignorance of mortal mind, its processes and falsely begotten phantasms of thought. By "reversal or revision" (Unity of Good, p. 24), the usurping doubt may be turned or deposed; and the truth it claimed to obscure or conceal will presently show clear.
