Seems to suggest that, yet other scriptures suggest never such a thing. As, "Who is he that condemns? It is Christ that died, yes rather, that is risen again, who is even at the right hand of God, who also makes intercession for us. Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?" Romans 8:34,35.
I like what Matthew Henry said in his classic commentary on this chapter of Romans 11, so here is an excerpt:
"For who hath known the mind of the Lord? Is there any creature made of his cabinet-council, or laid, as Christ was, in the bosom of the Father? Is there any to whom he has imparted his counsels, or that is able, upon the view of his providences, to know the way that he takes? There is so vast a distance and disproportion between God and man, between the Creator and the creature, as for ever excludes the thought of such an intimacy and familiarity. The apostle makes the same challenge (1 Co. 2:16 ):
“For who hath known the mind of the Lord? And yet there he adds, But we have the mind of Christ, which intimates that through Christ true believers, who have his Spirit, know so much of the mind of God as is necessary to their happiness. He that knew the mind of the Lord has declared him, John. 1:18 . And so, though we know not the mind of the Lord, yet, if we have the mind of Christ, we have enough. The secret of the Lord is with those that fear him, Ps. 25:14."
With praise to eternity!
