I'm really worried and confused. I feel sometimes like I went too far. Hebrews 6:4-6 seems to say I can't come back from backsliding (I even had a Taoist phase, I regret it so much. A lot of verses seem to say like IF you perservere and believe 100% to the end you'll be saved otherwise not), later it says there is no sacrifice for wilful sin. I know earlier today I had a feeling of "it's not that bad I can be forgiven later" and did something that I knew was sinful even though I repented I still feel awful because I don't know if that is blasphemy of the Holy Spirit or will be unforgiven on Judgement Day because no sacrifice for sins is left. I also have had a struggle with cuss words and one popped up when I was trying to contemplate the previous concern and I said in my mind (The Holy (blank) Spirit) and I instantly regretted it but I feel like the Bible says I am condemned.
