#22 In The Series "HEBREWS - The New And Living Way (And Why It's Better Than The Old Covenant)"
This may well be the most challenging teaching passage in the whole New Testament. The "Therefore..." introducing verse one is the writer's way of linking up these verses with the warning he launched into in 5:11-14 - "About this we have much to say, and it is hard to explain, since you have become dull of hearing. For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food,  for everyone who lives on milk is unskilled in the word of righteousness, since he is a child.  But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil."
Because our writer knows the charge of being "dull of hearing"(5:11) is easily ignored - that's what one would expect from someone dull of hearing - or even denied, he stays with this warning a little longer. Our text today is the Holy Spirit's tool for reminding dull of hearing, immature Christians theirs is a very dangerous position, so he forces them to consider the possible outcome - Hebrews 6:4-6 - "For it is impossible, in the case of those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit,  and have tasted the goodness of the word of God and the powers of the age to come,  and then have fallen away, to restore them again to repentance, since they are crucifying once again the Son of God to their own harm and holding him up to contempt."
