Therefore, brothers, since we have confidence to enter the Most Holy Place by the blood of Jesus, by a new and living way opened for us through the curtain, that is, his body…
Once a year on the Day of Atonement the high priest was allowed to enter into the Most Holy Place in the temple. There he would make a yearly sacrifice on behalf of the nation of Israel.
One of the many interesting things that happened at the time of Christ’s death was that the curtain that separated the Most Holy Place was ripped apart, both literally and spiritually.
We no longer have to approach God through a priest. Jesus made a new way for us to communicate with God. That new way is directly through Him. The book of Hebrews talks at length about how Jesus is now our high priest. Because of His sacrifice we can approach God.
In the Old Testament the high priest entered the Most Holy Place with fear. Even though it was a sacred duty that he performed, he also knew that one misstep could bring death. It was so serious that he had a rope tied around his ankle so that he may be pulled out in the event that he died.
Because of the new way that Jesus made, we do not have to approach God with fear and trembling. Our sins have been paid for in full. We can come to God in confidence because of Jesus.
