Heb. 7:28. But the word of the oath, which came after the law, appointed the Son, perfected forever.
Observe the oppositions. There the law, here the word of oath, that is, the most certain, the most true; there men, of course servants, here the Son, that is to say, the Lord; there the weak, that is, those who stumble, who have sins, who are subject to death — but here the one who is perfect forever, that is, eternal, almighty, not only now but always sinless. Therefore, if He is perfect, if He never sins, if He is always alive, then for what reason would He have offered a sacrifice for Himself, or indeed many times for others?
