What sins are unforgivable? Like God says,"Nope, that's it buddy you're done; Swan Song!"?

All sins are forgiven, no matter what those sins are, all sins past and future, by the person believing in Jesus for eternal life. Colossians 2:13, Acts 10:43. Jesus came to pay for all of our sins with His death and blood. So you must believe in Jesus for eternal life, without adding any of your own works, to be in heaven and not hell.

Nobody can be good enough to avoid hell. The truth is that death leads to immediate heaven or hell, depending only on whether the person believed in Jesus for eternal life, or not.

The truth is that Jesus loves you and wants to bless your life freely :) Most of all, Jesus wants you with Him forever, and not in hell. The truth is that every belief except one will lead to eternal torment in the lake of fire for every person. Because nothing pays for our sins except the death and blood of Jesus, the sacrifice of Jesus that is already accomplished by Him . Jesus loves you! The truth is that Jesus is God, and Jesus died on the cross to pay for all of our sins in full, and then Jesus resurrected from the dead. Nothing else pays for our sins, not works, not deeds, not religions. So the only way to heaven and to avoid hell, is by believing in Jesus for eternal life (John 6:47), without adding any of your own works (Romans 4:5). Believe in Jesus to take you to heaven, and you will be in heaven, no matter what, guaranteed. That easy, thanks to Jesus! Tell Jesus that you thank Him that you will be with Him in heaven when you die, because you believe in Jesus! It is too late to be saved, after death

There are none. God has already forgiven everybody for everything.

One listed as unforgivable is taking GOD's name in-vane!

I'm sure some moron, like CUT & PASTE CHRIS, will come in
and NOT offer you an answer, but throw you a mindless sermon to ignore!

Blasphemy of the Holy Spirit = To die without believing in Christ.

* It cannot apply to believers or anyone still living.

The only unforgivable sin is to deny the holy spirit to speak through you when being delivered up to the Antichrist.

I hope some of you are correct, cause I've done some crazy wacked out **** in my life and I'm surprised I'm still alive. Jesus must think I'm a good comedian/stunt man. Thank God For Jesus!

If you actually read the big book of fairy tales....I mean, the bible...the only "sin" that's unforgivable is nonbelief. It doesn't matter how evil, cruel, thieving, or murderous someone is, as long as they're a believer then everything else can be forgiven. According to some christians, Hitler is in heaven because he was a baptized catholic and a believer throughout his life. And no matter how good, kind, compassionate, giving, generous, caring, and helpful someone is, if the person isn't a believer then, according to the bible (to paraphrase) all of their righteous works are as worthless as filthy rags and they'll be condemned to eternal torture in hellfire. According to some christians, Carl Sagan and Steven Hawking are burning in hell despite all their contributions to the good of humanity. How fücked up is that?

Blasphemy against the holy spirit is an unforgivable sin. Blasphemy against the spirit emanates from the heart, revealing a malicious attitude and intent. The purposeful intent to oppose God’s holy spirit intensifies the seriousness of this sin.
It was the conduct of some religious leaders in his day that prompted Jesus to warn against the unforgivable sin. But they did not heed his warning. In fact, they had him killed. Later they heard undeniable evidence that the holy spirit had done something miraculous. They were told that Jesus had been brought back from the dead! It was clear that Jesus was the Christ! Still, they acted wickedly against the holy spirit by paying the Roman soldiers to lie about Jesus’ resurrection.—Matthew 28:11-15.

Rejecting the truth of Jesus Christ.

Denial of the holy spirit

I don't know how anyone can follow a religion that is willing to forgive murders, rapists, pedophiles, human traffickers, etc... but say the words "I deny god" and you are 100% bound for Hell.

Edit - denial of god/holy spirit as an unforgivable sin is called out in Mark, Matthew, and Luke. I am not sure why three someones (or one someone with three accounts) are thumbsdowning everyone who points this out.
