I believe that for a nation and for an
individual it is possible to continue in
sin until you cross over a mark. I do not
know where the mark is – I don’t pretend 
to be able to say when this takes place – but there is such a place. When you pass over that mark, it is not that the grace of God cannot reach you but that you cannot reach God for the simple reason that you have come to the place where you are hardened and in a state of unbelief which cannot be changed. This can be true of a nation, and it can be true of an individual.
J.Vernon McGee (1904-1988)
