Morality not to be relied on for life. Or, A brief discourse, discovering the…

1. In that moral obedience to which life was engaged in the First Covenant, there was required an exact conformity to the Rule therein given to man, which none of fallen men can attain unto. There was not only a morality required of man by the precept, for so there is still, and will be as long ⟨p. 17⟩as the special Government of God continues: but a constant life of happiness was Entailed upon it by promise, in case man had complied with it: but this was in the Covenant of Works, the language whereof we are told, in Rom. 10.5.

If we say that we have no sin▪ we deceive our selves, and the truth is not in us; and the wise man makes that challenge, Prov. 20.9. Who can say, I have made my heart clean, I am pure from my sin? Yea that is true of the best of men here,
