Haha, kidding? Santa is all about you being "nice," while God (at least the God of the Bible) extends what he gives to everyone regardless of how they lived their life. Santa would totally put coal in the poor prostitute's stocking.
Actually, the God of the Old Testament only spares good circumsised (if male) Jews from torment.
This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised. And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you. And he that is eight days old shall be circumcised among you, every man child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed. He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant. And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant.
So uncircumsised males who lived during the period from when god said this to Abraham at 75 years old (fairly early on, given that he is supposed to be 11 generations from Noah) and when Jesus decided that circumsision wasn't good enough any more (millions of people, easily - god killed a million Ethiopians in 2 Chronicles 14) didn't get into heaven.
He that is wounded in the stones, or hath his privy member cut off, shall not enter into the congregation of the LORD. A bastard shall not enter into the congregation of the LORD; even to his tenth generation shall he not enter into the congregation of the LORD. An Ammonite or Moabite shall not enter into the congregation of the LORD; even to their tenth generation shall they not enter into the congregation of the LORD for ever[.]
So if somebody mutilates your genitalia (at least if you were born before Acts 8), no heaven. If you were born out of wedlock, no heaven (even if anybody since your great-great-great-great-great-great-great-grandfather was born out of wedlock, no heaven). Not that anybody is currently ten generations from the Ammonites and Moabites, but if they were, no heaven.
It's kind of funny that Jesus was born to Mary and God (allegedly), who were not married; or, more likely, to Mary and Joseph, who had (allegedly) not consumated their betrothal when Jesus was conceived. In either case, Jesus was (allegedly) born out of wedlock, and hence he couldn't enter into the congregation of the lord. That must suck.
But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
But unfortunately, divorce and remarriage doesn't count, so anybody born of a parent who remarried (unless it was a husband whose wife cheated on them) is likewise condemned to the tenth generation. So a huge number of people are condemned to hell through no fault of their own, even if they were perfectly pure, simply because their parent(s) remarried.
Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
This verse is chronologically preceded by 1 Corinthians 6:9-11, which explains that people who used to commit these sins will not get to go to heaven. This verse further explains that people who still commit these sins, despite believing in god and being "born again", will not go to heaven. The ones he listed before are fornicators, idolaters, adulterers, "effeminate", "abusers of themselves with mankind" (male prostitutes who service other men), thieves, "covetous", drunkards, "revilers" (sometimes translated as "slanderers"), and extortioners. Doesn't seem that bad, really (except for the effeminate and covetous getting a raw deal). Except:
But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
So any man who looks at a woman who is not his wife in a sexual manner goes to hell if they die before confessing their sins. Seems a little harsh, no?
