Joe erroneously says:

Thus, my direct answer will be that I will pray that, "the eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints," (Eph 1:18).

That is another INDIRECT answer, for you have failed to reconcile or even address the statements you have both made and quoted that say the covenant of grace is both "inviolable" and violable, thus it is a clear falsehood.

And, for your information, "the eyes of my understanding have been enlightened" and I do "know what is the hope of His Calling" and most wonderfully, something of "the riches of the glory of His inheritance in the saints".

I just finished reading several of T. Goodwin's sermons on this very verse and find myself in complete agreement with his interpretation, both doctrinally and experientially, and thus, your evaluation, like others I have been a witness too, is lacking sorely in this important matter. Perhaps you would benefit from a reading of him?

In the meantime I leave you to your Covenant of Grace, "in some sense of the word", and hope your eternal salvation, on which it depends, is real, "in some sense of the word".

In Him,
