Imagine if you could not talk to God or connect with him personally. Imagine if to connect with God you had to go through somebody else! This was the way Israel functioned before Jesus. The High Priest was appointed to be the bridge between God and man, they would go into the temple, into the presence of God and sacrifice for all of Israel’s sins!
Now with Jesus, he does the same thing for us, but once and for all, he is our Great High Priest! Hebrews 4 and 7 show us that now we don’t have to go to a person to talk to God or be forgiven of sins, we can connect with God and receive forgiveness forever and ever!
