Once you are saved then you are going to heaven irrespective of if you die immediately after you've just committed a sin. The only way a christian can end up in hell is if the person loses his/her salvation. Seems ridiculous and unreasonable but that's just the truth. Most pastors try to motivate their members to live a holy life by making them scared of hell fire(which is understandable), but the truth still has to be told. The sin that takes people to hell is; "not believing on Jesus Christ and what He did for us on the cross" and not individual sins. Individual sins should not take christians to hell, but because of the erroneous doctrines in the church a lot of believers are perishing which ought not to be so. I pray God opens peoples eyes to see the truth. God bless you all.

But what happens to working out your salvation with fear and trembling?

vickyO: But what happens to working out your salvation with fear and trembling?

That verse is in philippians2:12, the whole book of phillipians(and chapter2 in particular) was written to admonish believers not to lose their salvation. What he meant by "work out your salvation with fear and trembling" is for them to submit themselves to the righteousness of Jesus Christ and not allow themselves to be deceived by erroneous doctrines(of circumcision). To have a better understanding of that verse read the book of galatians.

Even Jesus told people, go and sin no more so don't get the whole concept of salvation wrong.
As believers, we are to be Christ like.
Christ was without sin but we are mere humans so it's almost impossible to abstain from sin, i guess that's why the Holy Spirit was introduced.
As paul said shall we continue in sin for grace to abound?
Receiving the gift of salvation means taking up the challenge of becoming like Christ. It is not an avenue to wallow in sin.
Paul even told the early Christians that sin should be far from them.
What has light got to do with darkeness?

Am not saying a believer should continue to commit sin, sin actually gives the devil opportunity to afflict a believer(cos of conscience), there are also some other disadvantages that comes with a believer committing sin. But my point is that committing sin has nothing whatsoever to do with a believer going to heaven or not.

Kei144: Mt. 22:10 So the servants went out into the streets and gathered all the people they could find, both good and bad, and the wedding hall was filled with guests.
Mt. 22:11 “But when the king came in to see the guests, he noticed a man there who was not wearing wedding clothes.
Mt. 22:12 `Friend,’ he asked, `how did you get in here without wedding clothes?’ The man was speechless.
Mt. 22:13 “Then the king told the attendants, `Tie him hand and foot, and throw him outside, into the darkness, where there will be weeping and gnashing of teeth.’
Mt. 22:14 “For many are invited, but few are chosen.”

He. 10:26 If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left,
He. 10:27 but only a fearful expectation of judgment and of raging fire that will consume the enemies of God.
He. 10:28 Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses.
He. 10:29 How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace?
He. 10:30 For we know him who said, “It is mine to avenge; I will repay,” [Deut. 32:35] and again, “The Lord will judge his people.”
He. 10:31 It is a dreadful thing to fall into the hands of the living God.

That place you quoted in hebrews is talking about a christian rejecting Jesus Christ after already being saved. Or do you think it means that any christian that commits sin has no chance for repentance again.
