Clear as day, they must CHOOSE TO REPENT, or else they will not be saved. If they were elected and the "deal was sealed", THIS WARNING WOULD MAKE NO SENSE WHATSOEVER!!! Jesus is not irrational and does not make irrational statements, the way some men's doctrines are/do.

Good works, most especially our work of faith, are all a result of our regeneration by God; not a requirement for it.
Justification has been accomplished by Christ on the cross. Sanctification takes a life-time, "if God peradventure will give them repentance to the acknowledging of the truth."
