Seeing then that we have a great High Priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession. For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin. Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need (Heb 4:14-16 NKJ)
Therefore remember that you, once Gentiles in the flesh– who are called Uncircumcision by what is called the Circumcision made in the flesh by hands–that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world. But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. For He Himself is our peace, who has made both one and has broken down the middle wall of separation, (Eph 2:11-14 NKJ)
The book of Hebrews actually tells s that the earthly temple was a reproduction of the heavenly temple. The earthly temple had several different areas for the poor and needy, gentiles, women and Israelites. The closest you could go as a Jew would be the Court of Israel, where you could watch your sacrifice being prepared and offered, it was a half-way partition.
We read later in chapter 9 that Jesus, having risen from the dead and ascended into heaven, entered the heavenly temple “Not with the blood of goats and calves, but with His own blood, He entered the Most Holy Place once for all, having obtained eternal redemption. (Heb 9:12 NKJ) Not only did He obtain redemption, but as Paul reminds us in Ephesians, the wall of partition was removed. We can now come boldly to the throne of grace.
