6406. He shall ravage the heel. That this signifies a want of order thence in the natural, is evident from the signification of "ravaging," as being to drive away from truth (see just above, n. 6405), thus to disturb the order, or cause a want of order; and from the signification of "heel," as being the lowest natural (n. 259, 4938-4952). Hence it is plain that by "he shall ravage the heel" is signified a want of order in the natural. They who do works from truth and not yet from good, must needs cause in their natural a want of order, for works affect the natural; and consequently they must needs to this extent close their interiors; for the plane in which the interiors terminate is the natural, and if this is devoid of order, all that which flows in from the interiors also becomes devoid of order; and all that which is devoid of order is dark and opaque, so that they cannot see what is truth, but in this opacity and darkness they seize for truth what is not truth, and from this non-truth do their works. Moreover works are most necessary, for they are charity and faith in effect and in life, and who cannot see that without them there is no charity? Works are nothing but good and truth themselves in outward form; for good which is of the will, and truth which is of the understanding, when put forth into act, are called "works;" hence it is evident that such as are the good and truth, such are the works.
