I'm visiting a friend and her mom tried to debate me while I was here. She said she was 'set streight' by somebody she knows that told her she could lose her salvation with these verses in the bible. Hebrews Ch 6  For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,  And have tasted the good word of God, and the powers of the world to come,  If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame. I honestly don't understand what the verses mean and plan to ask my pastor when I return, but I told her the bible makes it VERY clear that you can't lose your salvation throughout the whole new testament! And gave her many examples, but there was no budging. So can anybody help shed some light on these verses? Thanks!
