Among all the things that a pastor will do on any given day, he must not lose sight of his one ultimate goal: the sanctification of God's people. This is the heart of God's purpose for Christians. John MacArthur calls pastors to remember what all the countless hours preparing sermons, visiting hospitals, counseling, conducting weddings, and more are all about, even when the finish line seems so far in the distance that they're tempted to give up. He encourages pastors with the power God gives them to place the sanctification of God's people at the center of their ministry.
