God rewards the leaders of His church for their faithfulness in caring for others. He will give them a crown.
1 Peter 5:
1 And now, a word to you who are elders in the churches. I, too, am an elder and a witness to the sufferings of Christ. And I, too, will share in his glory when he is revealed to the whole world. As a fellow elder, I appeal to you: 2 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. 3 Don’t lord it over the people assigned to your care, but lead them by your own good example. 4 And when the Great Shepherd appears, you will receive a crown of never-ending glory and honor.
5 In the same way, you who are younger must accept the authority of the elders. And all of you, dress yourselves in humility as you relate to one another, for
“God opposes the proud
but gives grace to the humble.”
6 So humble yourselves under the mighty power of God, and at the right time he will lift you up in honor. 7 Give all your worries and cares to God, for he cares about you.
