What does it mean that Christ is both the Good Shepherd and the Great Shepherd?

In the context of Scripture, Christ's role as the Good Shepherd emphasizes His sacrificial love for His sheep (John 10:11), while the designation of the Great Shepherd (Hebrews 13:20-21) refers to His resurrection power. The Good Shepherd's sacrifice secures redemption, whereas the Great Shepherd’s resurrection signifies His victory over death, providing the means for continual transformation and empowerment in the lives of believers. These roles are inseparable as they encapsulate the fullness of Christ's mediatorial work. Christians are reminded that they have a Savior who not only redeems but also sustains them through His living presence, guiding them in every aspect of their spiritual journey.
