The Perfect Savior
Hebrews 2:10-11a - "For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering. For he who sanctifies and those who are sanctified all have one source."
In the previous verse, through Jesus' substitutionary death and humiliation, he purchased his people and the glory and honor of exaltation for them. So why was this the way salvation had to be accomplished? It was fitting that Jesus be made the perfect savior through suffering because only by suffering for His people can He save them from their sins and be a merciful and faithful high priest. Jesus was perfect at all times of his life and never sinned. He was not made perfect then in the sense that He was purified from sin. Rather, he was made perfect in that He was given (bought) the eternal purification of His people. He did this by uniting himself to His people and dying in their place. Jesus (who sanctifies) and His people (who are sanctified by the Spirit of Jesus) are thus one and amazingly equally pure in the sight of the Father.
All things exist by and for Jesus, including salvation. It exists by His humble sacrifice of love for others and for His everlasting glory. God is not a passive spectator in the story of creation, but is the most active participant and the Star and Hero of it all! It was thus "fitting" that the Star appear at the climax to save the day!
