My post is based on:
Heb 6:4-6 KJV 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, (5) And have tasted the good word of God, and the powers of the world to come, (6) 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.
Heb 10:26-27 KJV For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, (27) But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
