Brothers and sisters:
Every priest stands daily at his ministry,
offering frequently those same sacrifices
that can never take away sins.
But this one offered one sacrifice for sins,
and took his seat forever at the right hand of God;
now he waits until his enemies are made his footstool.
For by one offering
he has made perfect forever those who are being consecrated.
Where there is forgiveness of these,
there is no longer offering for sin.
Hebrews 10:11-14, 18
The priest of Jesus' time, could not take away sins. No matter how many sacrifices were offered it just wasn't going to happen.
Jesus on the other hand, was able to wipe out our sins in one heroic act. He gave up his life to do this for us. Out of all the sacrifices that have ever been offered were never worthy enough to remove the taint of sin, but only one was.
When we sit back and think honestly about this sacrifice Jesus did for all of us. We would be a grateful people shouldn't we. How is it then that we hardly know him. What man would go to his death in such a fashion for the sake of freeing us of sin.
If we had to offer a person to free a country by his death would any do so, to free the country from the grip of evil? We have people who do sacrifice their lives for those who suffer in the many countries. But it does not wipe out sin.
Jesus went and gave up his life to perfect ours. While he awaits his enemies to stamp them out. Many who have chosen to follow the way of God have consecrated their lives to live as Jesus taught us to live. To love God and our neighbor.
