Heb. 9:26 for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself.
The daily offering of animal sacrifices was exhausting. Thousands of animals being slaughtered again and again was a constant reminder of the sinfulness of man and the consequences of that sin. Man was banished from fellowship with God. The very reason we were created, to know and enjoy God, was prevented by our sinful condition. The sacrifices were a daily reminder of that painful situation, the holy of holies kept the hope alive that one day man could walk with God again. In the tabernacle the blazing glory of God’s presence was present, the veil was the constant reminder to stay away. The blood of Christ ended all of that. By His one sacrifice sin was done away with. The way into the holiest was now finally open. He put sin away, animal offerings could never do that, the blood of God’s Son accomplished it. John said it like this in 1John 3:5 “You know that he appeared in order to take away sins, and in him there is no sin”. Here are some thoughts from Matthew Henry on the power of Christ’s blood.
“the sacrifice of Christ was the oblation of himself; he offered his own blood, truly called, by virtue of the hypostatical union, the blood of God; and therefore of infinite value. From the frequent repetition of the legal sacrifices. This showed the imperfection of that law; but it is the honor and perfection of Christ’s sacrifice that, being once offered, it was sufficient to all the ends of it; and indeed the contrary would have been absurd, for then he must have been still dying and rising again, and ascending and then again descending and dying; and the great work had been always in fieri—always doing, and always to do, but never finished, which would be as contrary to reason as it is to revelation, and to the dignity of his person: But now once in the end of the world hath he appeared, to put away sin by the sacrifice of himself.”
Sin has been finally put away by the death of God’s only Son. How does that effect me and you? First, I am no longer a slave of sin. The chains of my slavery are gone. Secondly, I can enjoy God and His love for me. This is why I was born, my purpose in life is finally being realized.
