The Office and Duties of High Priest – Part 1 – Hebrews 5:1-4

What is to be done with God on the account of sin, that it may be expiated and pardoned, and that the people at God who have sinned may be accepted with him and blessed, is all actually done for them by Jesus Christ, their high priest, in the sacrifice for sin which he offered on their behalf. He was ordained to do all things with God that were to be done for us; namely, that we might be pardoned, sanctified, and saved. This he undertook when he took his office upon him. His wisdom, faithfulness, and mercy, will not allow us to suppose that he hath left any thing undone that belonged thereunto. If anything be omitted, as good all were so: for none besides himself in heaven or earth could do aught in this matter. He hath therefore faithfully, mercifully, fully done all that was to be done with God on our behalf. Particularly, he hath offered that great sacrifice which was promised, expected, represented, from the foundation of the world, as the only means of reconciliation and peace between God and man. So saith the text he was to do: he was to offer sacrifice for sin. How he did it, and what he affected thereby, must be declared in our progress. For the present it may suffice, that there is no more to be done with God about sin, as to atonement, propitiation, and pardon. There needs no more sacrifice for it,—no masses, no merits, no works of our own. – John Owen
