let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
Hebrews 10:5-8 (NASB)
Therefore, when He comes into the world, He says, “SACRIFICE AND OFFERING YOU HAVE NOT DESIRED, BUT A BODY YOU HAVE PREPARED FOR ME; IN WHOLE BURNT OFFERINGS AND sacrifices FOR SIN YOU HAVE TAKEN NO PLEASURE. THEN I SAID, ‘BEHOLD, I HAVE COME (IN THE SCROLL OF THE BOOK IT IS WRITTEN OF ME) TO DO YOUR WILL, O GOD.’” After saying above, “SACRIFICES AND OFFERINGS AND WHOLE BURNT OFFERINGS AND sacrifices FOR SIN YOU HAVE NOT DESIRED, NOR HAVE YOU TAKEN PLEASURE in them” (which are offered according to the Law),
Hebrews 9:13-14 (NASB)
For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh, how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?
Hebrews 2:16-18 (NASB)
For assuredly He does not give help to angels, but He gives help to the descendant of Abraham. Therefore, He had to be made like His brethren in all things, so that He might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people. For since He Himself was tempted in that which He has suffered, He is able to come to the aid of those who are tempted.
