Sadly you have prejudged and not carefully investigated the scriptures as the investigative judgment is thoroughly grounded in a “thus sayeth the Lord”. We prayerfully hope that you will take the time to investigate for yourself and not let someone else do the thinking for you. Here is the plain scriptural evidences for the work of Christ as our high priest in the heavenly sanctuary which commenced in 1844. It explains Hebrews 9:12 quite nicely in the whole context of the Bible. You have to realize there is more than one throne, the eternal one and the temporary sanctuary throne. It is imperative to recognize this and the roles of each.

Yours in Christian concern, The Publishers

2 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
Hebrews 9:12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
Christ is of the priestly order of Melchizedec and not of the Aaronic priesthood.

Thank you for the encouragement and may God richly bless you as you study to show yourself approved unto Him and share this blessed hope with our beloved brethren in Laodicea.
