Hebrews 5:9

Verse 9. And being made perfect. That is, being made a complete Saviour--a Saviour fitted in all respects to redeem men. 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 Heb 2:10.

He became the Author, That is, he was the procuring cause (αιτιος) of salvation. It is to be traced wholly to his sufferings and death. Heb 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. Jn 14:15.

(b) "being made perfect" Heb 2:10
