It saved them from the penalty of their sins!
False religion can't accept this tremendous Gospel Truth which is this, every sinner Christ died for, or tasted death for, they have been saved from the penalty of their sins, Heb 1:3
Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high:
This purging of their sins is a completed perfect work Deut 32:4!
The word purge here is the greek word katharismos:
cleansing, purifying, purification, literal, ceremonial, or moral; met: expiation.
a cleansing from the guilt of sins
That is the guilt they contracted in Adam, and then their own personal sins guilt!The guilt acquired by sinning against Gods moral law.The Penal law has been satisfied for them by His God Honoring purging Death!
