Here, let's revive it:
Hebrews 6
[SUP]4 [/SUP]For
it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, [SUP]5 [/SUP]and have tasted the good word of God and the powers of the age to come, [SUP]6 [/SUP]if they fall away,[SUP][
b][/SUP] to renew them again to repentance, since they crucify again for themselves the Son of God, and put
Him to an open shame.
Verse 5 and 6 refers to people who were once believers.
