Do you know the purpose of the Great High Priest? Jesus IS The Great High Priest, in Heaven, as our advocate with The Father Almighty. He has taken the perfect blood into the Holy of Holies, IN HEAVEN, and put it upon the Mercy Seat, covering the laws.
When a person is born again, their want to changes, to want to conform to image of God's Son. we cannot do that on our own, so GOD's Spirit directs our growth in Jesus as a part of the Body of Christ / the Bride of Christ.
Thank you for asking. I trust the reply was not too convoluted. If there is any other that I may be able to address for you, don’t hesitate to ask. I may not have it all complete but I’ve been studying the topic for decades at this point.
