Reason to fear that God has given you up
If, after having heard these truths, and lived in a country where they are fully declared, you do not feel interested by them, you have reason to fear that God has given you up to hardness of heart and that the language of the prophet is fulfilled in you: “Go unto this people, and say, Hearing ye shall hear and not understand; and seeing, ye shall see, and not perceive: for the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed, lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them. Remember that, in Old-Testament times, when God blessed his people Israel with singular temporal blessings, he punished their transgressions mostly with temporal judgments; but now that we are favored with singular spiritual privileges, the neglect of them is commonly punished with spiritual judgments.
