I think I know how it happened but I have conflicting citings. D.A. Carson gives credit to McCheyne, I have it written down as John Owen.

"What a man is on his knees, in secret, before God that he is an no more".

I have an Owen quote that says

"A minister may fill his pews, his communion roll, the mouths of the public; but what that man is on his knees, in secret, before God Almighty, that he is, and no more."

Does anyone know where the McCheyne quote comes from? Carson does not cite it but attributes it to McCheyne. I have it written down as Owen--but also not cited. My guess is that McCheyne rephrased Owen's quote to make it more universal in scope. Anyone know?
