There is no paradox or contradiction:
… shepherd the flock of God that is among you, exercising oversight not under compulsion, but voluntarily, according to the will of God; and not for sordid gain, but with eagerness; nor yet as lording it over those allotted to your charge, but proving to be examples to the flock. And when the Chief Shepherd appears, you will receive the unfading crown of glory. Likewise, you who are younger, be subject to the elders. Clothe yourselves, all of you, with humility toward one another, for “God opposes the proud but gives grace to the humble.” – 1 Peter 5:1-5
The shepherd leads by choosing to serve, regardless of the reward, through a humble example to other members of God’s flock.
