HEBREWS 10:12
"But our High Priest offered Himself to God as a single sacrifice for sins, good for all time."
What do you think of a system that you have to repeat day after day to be affective? The priests offered sacrifices to God every day to atone for the sins of the people. The sacrifices were not effective for all time and the proof is that they had to be repeated time after time. Thus we see that the old covenant was merely a shadow of things to come, a template of what must be done to save sinners from death. The priests sacrifices could never take away the sins of the people. The was only one way for sins to be forgiven, ONCE AND FOR ALL!
Whereas the old covenant sacrifices were never perfect and never satisfied God, the New Covenant Sacrifice of the perfect Jesus Christ was. Christ was our High Priest on the order of Melchizedek and He was the perfect sacrifice that was without sin. Jesus offered Himself up to God as a single sacrifice for sin. That one one sacrifice was good for all time. As you know Jesus never had to sacrifice Himself again. After Jesus Sacrificed Himself He was seated in the place of honor at God's right hand. He remains there waiting for His enemies to be humbled under His feet.
By that one offering we were made Holy and perfect in the sight of God. There are three witnesses. The Holy Spirit testifies that this is so. God testifies that this is His beloved Son and He placed Him at His right Hand. Jesus testified to His being the perfect offering many times. Once He said why do you call me good, only one is good and that is God. Jesus also said He came to do God's perfect will. When called the Messiah He never denied it. So the perfect sinless offering was made in the body of Jesus Christ and is was ONCE AND FOR ALL!
