Bible Verses About Repentance: Denied to apostates

For as touching those who were once enlightened and tasted of the heavenly gift, and were made partakers of the Holy Spirit,

and tasted the good word of God, and the powers of the age to come,

and then fell away, it is impossible to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
