I hope you are wrong, otherwise I have no hope.
ShadowAce has neglected to notice to whom the "Letter to the Hebrews" was written. If one simply reads the letter the way it was written, the picture is rather different than his remarks. It is from one very astute Jewish (former) Pharisee, Paul, to the believing Jews (likely congregating in Jerusalem, still). Given this, one should notice that a very important fact about the Mosaic Law is on the table. Paul is referring to those who claim to embrace Jesus as the Messiah and the "fall back" to doing sacrifices at the temple for the remission of sin. He is saying to them, there is no longer any forgiveness in animal sacrifice...it is impossible now that the blood of the Son has been shed.
Those who continue are "close to being cursed". But, this is due to a very Jewish practice that many believing Jews simply could not abandon for fear of public rejection. Paul is arguing, there is no value in public acceptance from darkened Jews who do not know whence cometh their salvation.
The ones Jesus has chosen cannot be lost (John 6). If you find yourself trusting Him for your Rescue, not any activity, value, work you have done, then your "faith" has been granted you by God and you are among the elect.
Hold the Phone. Be encouraged Brother. Jesus is your hope. He’s the One to go to, not stupid man. Paul said he was the greatest of sinners and at first we think that his close walk with Christ made is “humanness” seem bleak. However, he didn’t say what his sins were. I can state this out of my own experience which is valid to me in my walk. In my 30 years of loving Him, serving Him and seeking Him and to be blessed as He has blessed me, I have fallen out of fellowship. TRUTH: (Job) He allows it to purify His Saints. Not by our strength or our will can we avoid sin, but by His Spirit. Times of testing are upon us all. He will not leave those that are His as orphans. But Grace will allow Him to finish the work He has started in us. Those who knew Him and deliberately and blatantly cut Him off is different than falling into temptation and sinning. His blood covers all transgressions if our heart hopes in Him for cleansing.
Don’t worry, I am proof he is wrong. :)
I don’t believe Hebrews 6 is addressing a brother or sister who is dismissed from fellowship with a church because of their sin. Paul addresses this and more importantly Jesus does. The church is to rejoice when the offender repents and the church is commanded to restore the brother or sister. I don’t think at all Hebrews 6 is addressing fellowship at all. If so, only the “church lady” would show up for services:)
