"13For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: 14How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?" (Hebrews 9: 13-14)
Before we can serve God, we have to know and believe in His love (1 John 4:1 6), that His blood has purged us from all sin, and that His blood cleanses us all the more (1 John 1: 7)
Too many Christians still treat the blood of bulls and goats with more respect than the blood of Jesus.
The blood of bulls and goats could atone for one year:
"29And this shall be a statute for ever unto you: that in the seventh month, on the tenth day of the month, ye shall afflict your souls, and do no work at all, whether it be one of your own country, or a stranger that sojourneth among you. . .34And this shall be an everlasting statute unto you, to make an atonement for the children of Israel for all their sins once a year. And he did as the LORD commanded Moses." (Leviticus 16: 29, 34)
Today, Christians believe that every time they sin, they lose fellowship with God, or they must atone for the sin by confession or good works.
First of all, there is no forgiveness of sins without the shedding of blood:
"And almost all things are by the law purged with blood; and without shedding of blood is no remission." (Hebrews 9: 22)
"It is impossible for the blood of bulls and goats to take away sins." (Hebrews 10: 4)
So, this idea that we pay for our sins by works or confession is false, misleading, and offensive to God.
Not the covering of fig leaves (works of self-righteousness), but the death of an animal gave Adam and Eve covering before God (Genesis 3)
Not our works, but the grace of God, paid for by His Son, saves us (Ephesians 2:8-9)
Today, we have the best covering, the robe of righteousness, which Christ Jesus have given us:
"I will greatly rejoice in the LORD, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels." (Isaiah 61: 10)
"But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:" (1 Corinthians 1: 30)
"To the praise of the glory of his grace, wherein he hath made us accepted in the beloved." (Ephesians 1: 6)
