That's a nice idea Danny, but unfortunately we continue to have free will (and the mortal temptataions that come with it) even after we accept Christ into our lives.
It's not just a nice idea, it's an idea that based in scripture. Yes we continue to have free will. And since we've been bought and paid for with a price, God can open a can of chastisement if He so chooses and if we warrant. God didn't make "everlasting" life dependent on our free will. Otherwise it wouldn't be "everlasting" life. It'd be, until you screw up again, life.
For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
A servant gets fired. An adopted child, doesn't get unadopted.
But if you want to put your faith in your own works and your own ability to be good instead of in Jesus, good luck with that.
