Questions that distract. Not that they are meaningless. But I find that they play no role in your relationship with God. How do you lose your salvation? You can't! Because as long as you confess your sins to Jesus, you WILL be forgiven? What about what was mentioned in Mark 3:29?
But whoever blasphemes against the Holy Spirit will never be forgiven; he is guilty of an eternal sin

Jesus was talking about the pharisees who were saying that Jesus was casting out demons with the help of Beelzebub (a demon)... Thats why Jesus said that they will never be forgiven. Because they were saying that Jesus, their source of forgiveness, was from the devil! So that ruled out them being forgiven. I also believe that the pharisees could be forgiven if they had confessed and repented. So the only unforgivable sin is if you choose not to ask for forgiveness.... AND THAT IN ITSELF IS FORGIVABLE IF YOU CONFESS AND REPENT!

So I conclude that there is no sin which is unforgivable.

If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
