Hebrews 11 talks about the triumph of faith. The main theme is faith,and we hear about great people of faith.
Hebrews 12 says, "…fixing our eyes on Jesus, the author and perfecter of faith, who for the joy set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God." It reminds us that Jesus is the author and perfecter of faith. Also, the last part says, "For consider Him who has endured such hostility by sinners against Himself, so that you will not grow weary and lose heart."
