I remember a few month ago that was very angry with God and testing him if he was real because at that time I was a new Christian and I was feeling a complete different person. I was kind of doubting God existence and I didn't know much about the bible and I attended church a few times. I remember blurting out something against the holy spirit when I was angry which I regret. At the moment I feel something different or thing change. I didn't know there was a sin. So far lately I haven't feel god in my presence or my holyspirt instead I keep on hearing my own voice of my head that I was going hell for committing that sin, I'm no longer save, or god isn't going to forgive me for that unforgiving sin or I will always feel guilty of that sin. I was thinking about going to back to my old life because I know that God will never forgive of that sin I committed and I will foreverly be lost.
