I think this Scripture applies to “Reformed Christians” who profess to be Reformed, but they are more concerned about appearing to be evangelical than they are concerned about maintaining pure true doctrine. They have lost the salt of Reformed Doctrine. They care more about not offending anyone and blending into the evangelical crowd who believe that God loves everyone and that Jesus died for everyone. They also want to show off their evangelical works which are often well-suited to photographs and videos to be praised by all.
They caved into the most popular evangelical doctrine (“Universal Atonement” – The Third Point of Arminianism in sharp contrast to “Limited Atonement” – The Third Point of Calvinism (“TULIP”). They may love to sing about the power in Christ’s blood. But, Christ’s blood according to their doctrine (as they claim, shed for everyone) by itself did not save, “purchase”, or “redeem” anyone, because they admit that most people are not saved. It is up to man to generate his own faith through his own free will in order to make Christ’s blood effective to save. They claim that the only difference between the saved and the unsaved is not Christ’s blood, because everyone gets the blood, but rather the only difference is whether or not a certain individual will generate his own faith through his own free will to make the blood effective. Man’s faith, not Christ’s blood, is the determining factor as to whether or not one will be saved.
This Scripture does not apply to the person who steadfastly rejects Christ. That person did not receive the knowledge of truth as stated in Hebrews 10:26. That person is not sanctified, so to speak, as is stated in Hebrews 10:29. That person does not talk about the blood of Christ. Rather, this Hebrews 10:26-31 Scripture speaks about those received or were exposed to knowledge of the truth and were sanctified so to speak but nevertheless denied the power of the blood and insulted the Spirit of grace. Rather, this Scripture applies to “Reformed Christians” who have lost their salt.
