Heb.6
[4] 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.
[18] That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:
[19] Which hope we have as an anchor of the soul, both sure and stedfast, and which entereth into that within the veil;
[20] Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec.
