The former priests were many in number, because they were prevented by death from continuing in office,  but he holds his priesthood permanently, because he continues forever.  Consequently, he is able to save to the uttermost those who draw near to God through him, since he always lives to make intercession for them.  For it was indeed fitting that we should have such a high priest, holy, innocent, unstained, separated from sinners, and exalted above the heavens.
(Hebrews 7:23-26 ESV)
It is fitting that we have a high priest such as Jesus. Without Him we can no closer come to the throne of God than we can to a raging fire. But because of the sweetness of the blood that dripped from the Savior’s body, we can with all purity, confidence, joy, and boldness walk under that crimson waterfall and commune with the Father.
It is fitting because we so desperately need it. Without Christ as our Great High Priest, we stand before judgment, awaiting the moment we are cast out to a land that we truly deserve. But, for those whose sins have been covered so fully by His blood, we draw near, no, closer than near, into the God who upholds the universe by the word of His power. He goes far beyond mild salvation; He makes far more of us than we could deserve in thousands of years of good deeds. He makes much of us in our making much of Him. He knows where we will find unlimited joy and satisfaction and He holds nothing back to give it to us. He gives us Himself. By His blood we are found in Him.
It is fitting. We do need it. He does give it. We do enjoy it. Permanently.
