Feed the flock of God which is among you, taking the oversight thereof, not by constraint, but willingly; not for filthy lucre, but of a ready mind; And when the chief Shepherd shall appear, ye shall receive a crown of glory that fadeth not away. Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time: But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, stablish, strengthen, settle you. To him be glory and dominion for ever and ever. Amen.
1 Peter 5:2, 4-4, 6, 10-11 KJV
