Hebrews 9:14

offered himself--The voluntary nature of the offering gives it especial efficacy. He "through the eternal Spirit," that is, His divine Spirit (Rom 1:4, in contrast to His "flesh," Heb 9:3; His Godhead, Ti1 3:16; Pe1 3:18), "His inner personality" [ALFORD], which gave a free consent to the act, offered Himself. The animals offered had no spirit or will to consent in the act of sacrifice; they were offered according to the law; they had a life neither enduring, nor of any intrinsic efficacy. But He from eternity, with His divine and everlasting Spirit, concurred with the Father's will of redemption by Him. His offering began on the altar of the cross, and was completed in His entering the holiest place with His blood. The eternity and infinitude of His divine Spirit (compare Heb 7:16) gives eternal ("eternal redemption," Heb 9:12, also compare Heb 9:15) and infinite merit to His offering, so that not even the infinite justice of God has any exception to take against it. It was "through His most burning love, flowing from His eternal Spirit," that He offered Himself [OECOLAMPADIUS]. without spot--The animal victims had to be without outward blemish; Christ on the cross was a victim inwardly and essentially stainless (Pe1 1:19). purge--purify from fear, guilt, alienation from Him, and selfishness, the source of dead works (Heb 9:22-23). your--The oldest manuscripts read "our." The Vulgate, however, supports English Version reading. conscience--moral religious consciousness.
