Well, if you check my exchange with drstevej above, you would see that we already hashed this out.
I have no doubt that those God "saves" or makes "His children" will remain that way. My problem, now and always, is identifying those with yourself. We should strive to make that so, but only by persevering can we know it to be so.
We are not saved because one day we decided to accept God. We are saved because God works through us for a lifetime in which we persevere.
