The only unforgivable sin is blaspheme, so far as I can see, none of you have committed that yet, so there is still hope. Sin is breaking God law, some sins are worst than others in man's eyes, but in God's eyes, if you break one you've broken them all. Sin can not enter into heaven, but sin can be forgiven, that's why Jesus came to pay for man's sin, but you have to believe it and accept it or else you are still in your sin and the punishment is death, the second death. I have done what is required of me, I have told you the truth, if you choose to disbelieve it, so be it.
