Hebrews 2:9-10

Hebrews 2:9-10. That he by the grace of God should taste death for every man. 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.

Not that Christ needed to be made perfect in nature, but perfect in his capacity to be the Captain of our salvation, complete in all the offices which he sustains toward his redeemed people. He must be a sufferer that he may be a sympathizer; and hence his sufferings made him perfect.
