Yahweh said to me, "Amos, what do you see?" I said, "A plumb line." Then the Lord said, "Behold, I will set a plumb line in the midst of my people Israel. I will not again pass by them any more.
 Hence they both work so as to help each other on; because the grossness of superstition provokes and produces infidelity as a reaction, whilst the barren misery and desolation of infidelity exposes souls to the high claims of superstition to meet the cravings of the natural heart, where God is not known and self is unjudged. Thus scepticism leads persons indirectly to superstition. The cold blank of infidelity, the hopeless absence of truth, its negative character in short causes the heart to yearn for something positive, something to lean on; and if they have not God and His word to believe, by an abuse of His name they have man at any rate to confess to. Thus to regard man is superstition; but it is evident that the deliverance from it is not giving up scripture, but bowing to God instead of man.
