Translation
how much more the blood of CHRIST, who through the eternal Spirit, offered himself to THEOS without blemish, will purify our moral and spiritual consciousness from dead works in order to serve the living THEOS.
Paraphrase
Since THE ANOINTED MESSIAH offered himself to THE OWNER AND RULER OF ALL THINGS through the agency of the very Spirit of THAT RULER Himself, and did so in a way that was acceptable to Him, His blood must be capable of fully purifying our inner being and our will from acts that lead to death so we can serve the OWNER AND RULER who is alive.
