In broad terms these two chapters deal with what the Holy of Holies represents, what the blood of Christ meant to the sacrificial system established in the Old Testament and Christ being the final sacrifice for sins. In 10:19-25 the author of the book of Hebrews reiterates from previous chapters that we we can enter the Holy of Holies that is normally reserved for the High Priest and for him only once a year. We are able to do this because Christ’s sacrifice did not simply cover our sins, as the previous ones did, but actually cleansed us from sin. So, we are told that not only has Christ’s sacrifice cleansed us from our sins, it also cleanses our minds from a Guilty Conscience. I believe that this is the most missed part of this passage. Many Christian’s, myself included, end up being held back from all of God’s grace and power because we hold onto the past sins by thinking we are not good enough, haven’t done enough, failed to read the Bible enough, etc. to be used by God and to be blessed by God. I have been held back by my own past mistakes, not by God, but by myself. There is a line in the movie The Matrix when Neo is in the house of the oracle, he encounters a young boy that is holding a spoon and appears to be bending it with his mind. Neo asks how he is doing that and the boy says “do not try to bend the spoon that is impossible. Instead only try to realize the truth…There is no spoon” The reality of my situation and yours is that there is NO PAST!!! We need to realize the truth, since there is no past we should boldly approach the Throne of God, not because we have done something to earn it but because God has forgotten our sins, Hebrews 8:12 “For I will forgive their wickedness and will remember their sins no more”. By the blood of Christ He has not simply covered our sins but has cleansed them away and cleansed our guilty conscience away so they are no more.
So I urge us as Christians to quit letting Satan beat us up with a weapon, our past, that doesn’t exist to God. We are in effect handing the enemy an invisible weapon and allowing him to defeat us with it. Christ died to erase those sins, don’t let the enemy use a part of our minds to defeat us.
