What is the difference between the elect and the reprobate?

Some of the neo-preachers want to say that the difference between the elect and the reprobate remain to be works done by them. This is not so. The difference between the elect and the reprobate remains to be Christ and his works.

"Whence should it be, in respect of the event, that the elect and reprobate differ one from another? The difference lies in this, the elect shall be saved, and the reprobate shall be damned; the immediate cause is this, the reprobate bears his own sin, by reason of which he bears his ensuing damnation; the elect person bears not his own sin, and so there is nothing found against him, for which he should be damned." - Tobias Crisp, Christ Alone Exalted, vol 2, pg. 81
