All right... provides great insight but let me rephrase into 3 scenarios. Apologies if it is lengthy. The main question at hand is can/will Jesus REALLY forgive all your sins, regardless of how bad they may be, if you truly repent? As I see, there are 2 groups of people right now.
GROUP 1
Jesus will forgive your 'normal' sins but if you go worship the devil, offer sacrifices to the devil, kill your children, start the holocaust, burn down churches and commit over 9000 more horrible deeds, no matter how hard you repent afters, don't count on being forgiven.
GROUP 2 - what I believe, because "though your sins are red as crimson, Jesus will wash you as white as snow" or something mentioned somewhere. I assume this means any sin.
No matter what you do, be it worshiping the devil for a time of your life, torturing and killing an entire nation, if you truly repent, all your sins will be washed away. Sure there will be earthly consequences, but this day, you have received life and forgiveness.
There are really people who have done really bad stuff, and have turned around. However the issue I'm inquiring about specifically is perhaps the greatest sin man could commit - willfully and knowingly prostrating himself before the devil, but few years later, regrets it and repents.
Then again, there is debate as to what is CONSIDERED worshiping the devil. There are those who say just any sin would suffice as temporarily worshiping the devil, others that say one must totally reject God, and yet others who say anyone who is of another religion is essentially worshiping the devil (as opposed to them just trying and failing to worship God).
For the sake of this debate, I shall use the WORST case imaginable, a previously staunch christian, Bob, who is swept away by greed, knowingly rejecting and cursing God, calling upon satan, negotiating the price as an acolyte (eternal damnation as satan's slave), but after a few years, recognizes his folly, and now wonders if he can ever be a Christian again.
Scenario 1 (worshiping the devil, nothing more, now renounces his ways)-Lets say Bob, who was a Christian (and so knew what was before him) for some reason got involved in some satan worshiping cult (it actually exists, though I've never met one). Eventually, after several years, he mended his ways, cuts off all contact with the cult and picks up the bible. Few years later, he wants to be baptized, renounces satan, and wish to lead a godly life. He realizes he had done something stupid, regrets it profoundly, and seeks forgiveness and a new life.
Scenario 2 (same as with scenario 1, but plus more evil but reversable)-In exchange for power/money/whatever, out of desperation or just greed, Bob promises to worship satan in exchange for deliverance from current material hardships. Lo and behold, satan thinks it is an irresistable offer and grants Bob's request. Sure enough, Bob got to keep his job, AT THE COST OF HIM WILLFULLY GETTING HIS PAL PETE FIRED AND THROWN IN PRISON. Bob was a Christian, aware that it was bad all along. However, he was overcome with greed and desperation, and really felt it was worth it, at that time. A year later, Bob curses himself and wishes to change. He finally picks up the bible again, goes to church, begs for forgiveness, distances himself from his satanist friends, and admits whatever backstabbing he did, getting Pete reinstated in his job and him fired and facing the consequences (reversable damage - somewhat). Now in jail, Bob ponders his salvation and pledges to do good with his life once he's out.
Scenario 3 (same as scenario 1, but A TON MORE EVIL, we're talking Hitler grade here, irreversible damage)
Bob and Pete were best pals, they grew up and even attended church together. However eventually Bob covets Pete's position and willfully made a deal with Satan for a promotion to replace Pete, at the expense of getting Pete framed for mass murder which he commited (to frame Pete for it). Pete is executed, Bob didn't feel a tinge of remorse, till 10 years later, where he now feels very guilty and wishes to mend his ways, but recognizes he can never bring that entire orphanage of kids he murdered as well as Pete back. He now knows he's not worthy to live, but still hopes that somewhere, somehow, Jesus could forgive him. He admits it, but death penalty now abolished, and because he was so remorseful and whatever (ok lets just say he was let of easy, doesn't happen IRL but just for the scenario) he served 10 years jail and got out. He is now a much better person, but forever running from his past. He tries to lead a honest, productive life now, but still occasionally fall to life's temptations (who doesn't stray now and then?). However, he now wishes to be a Christian again, and now wonders if that is possible, and wonders if Jesus can really wash away his sins.
IN CASE IT WASN'T CLEAR ENOUGH
@ryan
Your soul is tossed in the lake of fire due to rejecting God, not because you "gave" it to the devil.
Yeah I'm asking what happens if after rejecting God, you turn around and mend your ways, now wanting to be re-baptized.
And just how do we get that mark thing now? Don't see anyone with a mark on their forehead. What if you turned to the darkness before being saved (if that is possible)?
