Jeremiah Burroughs (The Saints Treasury, p. 11):
[O]bserve how the Scripture sets out the spirits of men after their Idoll gods, in regard of the cost they are willing to bestow upon them. Isa. 46:6. They shall lavish gold out of the bag, and weigh silver in the ballance, and hire a goldsmith, and he maketh it a god. They care not what cost they are at to worship their Idols. O what a shame would it be if we should not be willing to part with much of our estates for the true worship of the true God: and though we should lose our estates, yet if we can serve God better, and in a purer way, we should be content; for Idolaters will lavish gold out of the bag upon their Idols. Now there is none like to our God; therefore it is a shame that they should doe more for their gods then we doe for ours. And then what are Idolaters willing to suffer for their gods? 1 Kings 18:28 how did Baals Priests there cut themselves after their manner, with Knives and Lancers, till the blood gushed out, to shew their respect to their Idols! let us then be willing to suffer any thing that God calls us to. And how constant were they to their Idols! therefore sayes God, Jer. 2:10, 11. Consider diligently and see, if there be such a thing: hath a Nation changed their gods which are yet no gods? but my people have changed their glory for that which doth not profit; how ill doth God take this that Idolaters should not change their gods that are infinitely below him, and yet that his people should change their God who is infinitely above them?
