When the Chief Shepherd Appears

Except pastors retain this end in view, it can by no means be that they will in good earnest proceed in the course of their calling, but will, on the contrary, become often faint; for there are innumerable hindrances which are sufficient to discourage the most prudent. They have often to do with ungrateful men, from whom they receive an unworthy reward; long and great labors are often in vain; Satan sometimes prevails in his wicked devices. Lest then, the faithful servant of Christ should be broken down, there is for him one and only one remedy,–to turn his eyes to the coming of Christ.

From John Calvin’s commentary on 1 Peter 5, specifically verse 4: and when the Chief Shepherd appears.
