Hebrews 5:9

Became - Was exactly suited for; was fitting.

And being made perfect - Και τελειωθεις· And having finished all - having died and risen again. Τελειωθηναι signifies to have obtained the goal; to have ended one's labor, and enjoyed the fruits of it. Hebrews 12:23 : The spirits of just men made perfect, πνευμασι δικαιων τετελειωμενων, means the souls of those who have gained the goal, and obtained the prize. So, when Christ had finished his course of tremendous sufferings, and consummated the whole by his death and resurrection, he became αιτιος σωτηριας αιωνιου, the cause of eternal salvation unto all them who obey him. He was consecrated both highs priest and sacrifice by his offering upon the cross.

"In this verse," says Dr. Macknight, "three things are clearly stated:

1. That obedience to Christ is equally necessary to salvation with believing on him.

2. That he was made perfect as a high priest by offering himself a sacrifice for sin, Hebrews 8:3.

3. That, by the merit of that sacrifice, he hath obtained pardon and eternal life for them who obey him."

He tasted death for every man; but he is the author and cause of eternal salvation only to them who obey him. It is not merely believers, but obedient believers, that shall be finally saved. Therefore this text is an absolute, unimpeachable evidence, that it is not the imputed obedience of Christ that saves any man. Christ has bought men by his blood; and by the infinite merit of his death he has purchased for them an endless glory; but, in order to be prepared for it, the sinner must, through that grace which God withholds from no man, repent, turn from sin, believe on Jesus as being a sufficient ransom and sacrifice for his soul, receive the gift of the Holy Ghost, be a worker together with him, walk in conformity to the Divine will through this Divine aid, and continue faithful unto death, through him, out of whose fullness he may receive grace upon grace.

And being made perfect - That is, being made a "complete" Saviour - a Saviour suited in all respects to redeem people. Sufferings were necessary to the "completeness" or the "finish" of his character as a Saviour, not to his moral perfection, for he was always without sin; see this explained in the notes on Hebrews 2:10.

He became the author - That is, he was the procuring cause (αἴτιος aitios) of salvation. It is to be traced wholly to his sufferings and death; see the note, Hebrews 2:10. "Unto all them that obey him." It is not to save those who live in sin. Only those who "obey" him have any evidence that they will be saved; see the note, John 14:15.

5:9 And being perfected - By sufferings, Hebrews 2:10 ; brought through all to glory.He became the author - The procuring and efficient cause.Of eternal salvation to all that obey him - By doing and suffering his whole will.
