If a Christian backslides, a study group said there is no more salvation because it is like crucifying Jesus all over again. So if someone is backslidden and has no chance to go to Heaven to be with God and loved ones then why not die now and get it over with instead of living in Hell on earth knowing you are going to Hell when you die so just go now and get it over with right?
The idea that people who backslide have no hope comes from a number of verses in the New Testament. Hebrews 6:5-8; Hebrews 10:26,29; 1 John 5:16-17.
Hebrews 6:6, is talking about people who had once been enlightened, believed in God, received the gift of the Holy Spirit, and the powers of the age to come. If they for instance had performed miracles by the power of God's Holy Spirit, then turned away, and rejected God's ways and set their hearts against him, then they are said to "crucify the Son of God on their own account", and "bear thorns and thistles" instead of fruit. It is impossible to get someone like that to repent while ever they are in that frame of mind, not because God doesn't want them back, but because of their own attitude, and experience shows that there are very few like that who come back to God.
- "If we deliberately keep on sinning, after we have received the knowledge of the truth, no sacrifice for sins is left, but only a fearful expectation of judgement, and of raging fire that will consume the enemies of God. Anyone who rejected the Law of Moses died without mercy on the testimony of two or three witnesses. How much more severely do you think a man deserves to be punished who has trampled the Son of God underfoot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace." Hebrews 10:26-29
1 John 5:16-17: talks about sins that can be forgiven, and sins that lead to death. And goes on to say in verse [1 John 5:]18 "We know that any one born of God does not continue to sin;"
The sum total of the above verses is that those who turn away from Jesus and continue to reject him, only have the prospect of being rejected at the judgement seat of Christ, being punished and suffering the second death which lasts forever.
This is quite different to a person who has slid backwards through weakness and not through deliberate rebellion. 1 John 1:8-9 says "If we say that we have no sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us all from unrighteousness."
And even the rebellious if they should repent, and start following God's ways again, can have their sins covered. See James 5:19-20.
