I agree with most of the video, however I am not so sure of the interpretation at the end. It could be true but I see it in the following way.
Heb 6:6 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.
In order to crucify afresh the son of God, that sacrifice must be no longer available. But we know:
Heb 9:27-28 And as it is appointed unto men once to die, but after this the judgment: So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
We see from Hebrews 9:27-28 that the cross covers a lifetime of sins. All of our sins are forgiven in this life time.
So in order for the sacrifice to be no longer available, a person must have died in their sins. In that state their no no room found to repent, their is no second sacrifice.
