What does the Bible say about the way into the holiest?

According to Hebrews 9:6-10, the author explains that the way into the holiest of all was not yet revealed during the time of the old tabernacle, which stood as a symbol. The priest would enter the holy place once a year with blood, signifying that access to God was conditioned upon sacrifice. The text indicates that these former ordinances were inadequate for perfecting the conscience and were ultimately fulfilled in Christ, who is the true and perfect High Priest. Through His sacrifice, believers now have direct access to the Father, as He has opened the way for us by His blood.
