What if Hebrew 6 is not a hypothetical or talking about sinning but what if it is conditions set down by God for any who want to willingly leave the faith??? Since we have free will would that mean that one could choose to leave the Lord??? I don’t mean by just backsliding but willfully choosing to leave. what if Hebrews 6 is saying ‘ok if you want to leave having known the truth you can BUT be advised you can NOT come back for to allow you back would mean Christ would have to be crucified again.’
 
Some might say the person never really chose the Lord so they thus could not leave the Lord. if true how can you tell who is and isn’t Christian???  how can you tell then who is a backslidden Christian and who never was a Christian?? Keep in mind we are told a good tree can NOT produce bad fruit and a bad tree can NOT produce good fruit. I looked at the entry for Charles Schultz and was surprised after being a Sunday school teacher and so many peanuts cartoons and strips with Christian themes and bible verses that at the end of his life he was a secular humanist. He obviously had good fruit so one can only conclude he was Christian and then left the faith.
