“…And he said to me, “This is the Most Holy Place.”
The deepest chamber within the temple housed the Ark of God and the the Mercy Seat. It was here, the high priest would enter only once a year to bring the blood of the sacrifice, and intercede on behalf of the Nation. It was here, God had originally explained to Moses, they could meet with the Lord and talk to Him about anything.
Exodus 25:22 “And there I will meet with you, and I will speak with you from above the mercy seat, from between the two cherubim which are on the ark of the Testimony, about everything which I will give you in commandment to the children of Israel.”
I think it is worth noting, this chamber is called the Holiest Place. It is only in holiness that we can meet with God. That is particularly concerning when we realize we are not holy. The prophet made it abundantly clear, even our best attempts ar doing good, lack true holiness in the sight of God.
Isaiah 64:6 “But we are all like an unclean thing, and all our righteousnesses are like filthy rags; we all fade as a leaf, and our iniquities, like the wind! Have taken us away.”
If God is holy, the meeting place between God and man is holy. We, at our best, are not holy; we are in need of help. That is where the cross comes in. Under the old covenant, this was solved through sacrifice on the altar. The priest would confess his sins and that of the people, and would enter the holiest place. Now under the new covenant, this is solved by Christ. His sacrifice provides atonement for all our sins. We, like the priest, must accept the sacrifice, by accepting Christ and confessing our sin. When we do, we are forgiven, made holy, and have access to God.
If you have received Christ, there is nothing keeping you from the holy meeting place. You may attend there regularly, bringing yourself, your life and your needs before the Lord.
