“Since then we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession.” Hebrews 4:14
Imagine being a small child in ancient Israel on the Day of Atonement.
As a child you are not required to fast, but all the grown-ups do because they say God had commanded that they fast. Maybe you would eat a little less because you felt badly eating when others could not - and it did make you feel grown up too.
The really big part of the day was when the high priest went into the holy of holies to meet with God. He went in there only once a year to present a sacrifice for the sins of all the people. It was awesome. The other priests put a bell on his garment so they could hear him.
Deep down inside you, you are glad this solemn event occurred only once each year.
Read what the New Testament author wrote:
“But when Christ appeared as a high priest of the good things to come, He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation; and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all, having obtained eternal redemption.” Hebrews 9:11-12
Jesus, your High Priest, needed no sacrifice for Himself. He did not enter the holy of holies, but the very presence of God in heaven. There He lives to intercede for you.
You have been freed to serve the living God. Praise Him!
