I cannot say all people that commit suicide are automatically going to hell. But I cannot say they wouldn't either. But I certainly am not going to commit suicide to find out.
But I can say what the Bible tells me concerning repentance in relation to sin concerning believers, according to 1st John 1:
7. But if we salk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
8. If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
10. If we say that we have not sinned, we make him a liar, and his word is not in us.
I believe those scriptures are written to believers that already are walking in the light, yet are also aware that they can be tempted to sin yet by their own lust of flesh. But even though tempted, if they confess their sins to the Lord, He will forgive them. but not only forgive them, but also cleanse them from all unrighteousness too, as they continue to grow in Him staying in that light. Because it is that light that reveals all fleshly lusts. And it is also that light that cleanses them of that lust as well.
No place that I know of does it ever say that beginning repentance means you are forgiven of all past sins as well as future ones though. But if someone does know of such, please tell me where it is.
luv ya,
