Care for the flock that God has entrusted to you. Watch over it willingly, not grudgingly—not for what you will get out of it, but because you are eager to serve God. Don’t lord it over the people assigned to your care, but lead them by your own good example. And when the Great Shepherd appears, you will receive a crown of never-ending glory and honor.
1 Peter 5
