Someone who is truly regenerated will not live like that.
That example does not negate the truth that our sin cannot separate the believer from God.
Calvinism has spiritual/intellectual problems as well in light of all the Catholic bashing, Baptist bashing, Luther bashing, etc... constantly being bandied about. Christ did all the work, however the theology of the Christian has no responsibility how they act is extremely short-sighted. Jesus is Lord's verse on post #3 pointed out the futility of that theology.
As for the verse in post three, which I just addressed. If you hold to that, does that mean you also hold to what it says that you have ONE chance at salvation and if you blow it, that's it? You're done? No more chances for you again ever?
Is that what you believe, too?
Also unbelievers make mince meat of the hypocrisy as well which was a point in n post #3. Anton LeVey started his perverted “ministry for Satan”/humanist “church” based on his observance of supposedly Christian people living in debauchery for 6 days a week, but asking forgiveness every Sunday morning and just repeating the cycle without any intention of really trying to repent.
