Hebrews 10:26 says: "If we sin willfully after that we have received the knowledge of the truth there remaineth no more sacrifice for sins," KJV
Obviously, willful sinners are deplorable to our Creator. (Think of someone accidentally kills someone innocent, not willfully, versus someone who willfully and unrepentantly kills an innocent. We would think most reprehensible.)
There sins are intentional and practiced. They know God's requirements but deliberately disobey them.
This shows no regard for the precious gift through the shed blood of Jesus Christ.
True it shows no regard for the precious gift through the shed blood of Jesus Christ. That was the precise sin Heb 10:26 is speaking of...the sin of spurning His blood and going back to the Mosaic system of animal sacrifice due to pressure of persecution.
