Hebrews 2:9-10 "But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man. (10) For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings."
We are not told the author of the book of Hebrews, but he is very logical in the way he is laying the groundwork for the entire book.
He has established both the authority and the eternal aspect of the person of the Lord Jesus Christ. Now the writer is laying out the manner in which Jesus accomplished redemption for His people.
Though He is the eternal Son of God, Jesus was made a little lower than the angels. He made Himself of no reputation and took upon Himself the form of a servant. See Philippians chapter two.
Why did He do this? Why was it necessary for Him to do this? Let Scripture answer these questions. "Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned. (Romans 5:12) "For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous." (Romans 5:19) "For since by man came death, by man came also the resurrection of the dead." (1 Corinthians 15:21) Jesus, the Son of God, took upon Himself human flesh to pay your debt.
"For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings." (Hebrews 2:10) Do not misread this verse. There were no imperfections in Jesus. The word, perfect, means to consummate, complete, it carries the meaning of fulfilling the work He came to perform.
In order to complete the work of redemption, Jesus had to suffer many things including the stripes on His back, the scars of the crown of thorns, the nails through His hands and feet, and the spier in His side.
He did it! He paid the price for your ransom. His death paid the price for your sin debt. He paid it all. Rejoice in His great love and grace. He did it for you!
