Multiple commentators emphasize that Jesus redirects the disciples' joy. While they were excited about their newfound power over spirits, Jesus points them to a far greater and more permanent reality. The ultimate source of a believer's joy isn't found in spiritual gifts, talents, or victories, but in the assurance of salvation and a personal relationship with God. As Albert Barnes notes, having a 'title to everlasting life' is of far more value than any earthly honor or power.
