Bible Verses About Repentance: Denied to apostates

For when people have once been enlightened, tasted the heavenly gift, become sharers in the Ruach HaKodesh,

and tasted the goodness of God’s Word and the powers of the ‘olam haba —

and then have fallen away — it is impossible to renew them so that they turn from their sin, as long as for themselves they keep executing the Son of God on the stake all over again and keep holding him up to public contempt.
