The Resistance therefore acts as a restricting force, limiting the
extent to which the power of the original Electro-motive force shall be
delivered at the point where the work is to be done, but at the same
time no delivery at that point could be effected without it; so the
Resistance also has a necessary part to play in the working of the
circuit. Now if we want to translate the formula C = E/R into terms of
spiritual force we may put it thus: E stands for the limitless Potential
of the Eternal Spirit; C stands for the current flowing from it; and R
stands for the localizing quality of our thought. We cannot entirely
dispense with this localizing quality, for our whole purpose is to
transmute the _unlimited_, undifferentiated power, which subsists in the
Eternal Substantive of Spirit, into a particular differentiated mode of
action, which therefore implies a corresponding centralization. This is
the proper function of our thought. It is this compressing power which,
as I said above, the Hebrew renders by the word "_hoshech_" in the
opening verses of Genesis, and which is the necessary complementary to
the converse expanding power or "_rouah_." It takes the co-operation of
the two to produce any results.

Restricted, then, to its proper function our R or condensing quality is
an essential factor in the work. But if it be allowed to take the form
of doubt or unbelief, then it renders the flow of the current from the
Spirit ineffective to the extent to which the doubt is entertained; and
if doubt be allowed to degenerate into total unbelief and denial of the
Power of the Spirit, we thereby cancel the originating force altogether.
To put it in terms of the electrical formula, we make R greater than E,
in which case no current can flow. We thus find that the words
"According to your faith be it unto you" are actually the statement of a
Mathematical Law, having nothing vague about them. This may be a
somewhat original application of Ohm's Law, but the parallel is so
