What does it mean that Christ is a prosperous servant?

The term 'prosperous servant' refers to Christ’s successful fulfillment of His mission to save His people. Just as Joseph in Egypt was entrusted with tasks that prospered, so too did Christ succeed in His endeavor to redeem sinners and grant them eternal life. In John 17:2, it states that the Father has given Him power over all flesh to grant eternal life to those who believe. This emphasizes that through Christ, believers receive spiritual blessings and assurance, illustrating the abundant fruit of His service.
