Read the bible. The only thing you need to do to be a christian is to believe in the holly spirit.
You can be a killer, a rapist, whatever. As long as you believe you go to heaven.
The only sin that can send you to hell is to denounce the holly spirit.
One can't believe on the Holy Spirit except that He gets the Word of God into himself/herself in some way... and I don't mean by eating paper. Why? It is only the Holy Spirit Who works faith in a person's heart, and the Holy Spirit only works through the Word of God.
Besides, anybody that becomes evil, or continues in his evil ways intentionally, disrupts his faith. Depending on how serious his crime, or how intentional, his faith is going bye-bye, or it was never there in the first place.
Since all people sin - even the real Christians - one needs to daily maintain at least the reminder of some of the words he formerly read in the Bible, or heard being read to him, if he wants to maintain his faith.
You can. Again read the bible.
The only sin that can condemn to hell is to denounce the holly spirit.
You can kill and rape all you want
And no I'm not going to help by quoting this time. read the damn book and maybe you will see the light
I have many times. That's why I'm an atheist
But God makes the judgment whether or not you have remained in saving faith.
The only sin that is unforgiven is locked in unbelief with regard to Jesus salvation.
The salvation of God was put into place to save all people, if they accept the salvation of God, which is the salvation of Jesus. No matter the sin, you can be saved. But salvation isn't salvation of the righteous. It is salvation of sinners.
If you continue sinning after receiving salvation, then you have not really received salvation. You can't receive salvation and keep on sinning at the same time. Read the book of First John near the end of the Bible.
However, nobody stops sinning entirely. And this is the reason that God is the judge about each person individually. Only God can tell if a person is of the heart and mind that keeps him saved, even though he sins after being saved.
As for you, have you already locked yourself into unbelief? Read Hebrews in the Bible to see that if a person once was saved, and then falls away, it is impossible for him to be brought back to salvation.
