For it was fitting that God, for whom and through whom everything exists, in order to lead many [of His] children to glory [i.e., heaven], would make the author [or, pioneer] of their salvation [i.e., Jesus] completely [qualified] through [His] sufferings.

So, we should leave the basic principles of Christ's teaching and go on to maturity. [We should] not lay again a foundation of repentance [i.e., turning away] from deeds of death [i.e., acts that lead to spiritual death or that spring from a spiritually dead person], and of faith in God;

[It will] not be like the Agreement that I made with their forefathers on the day I took them by the hand to lead them out of the country of Egypt. For they did not [continue to] keep my Agreement, so I did not regard them [as acceptable], says the Lord.

how much more will the blood of Christ, who through the eternal Holy Spirit [or, His eternal Spirit] offered Himself without [moral] blemish to God, cleanse our consciences from deeds which lead to [spiritual] death to serve the living God?
