“Consider, …the reasons why the Lord is pleased to have have people exercised, troubled, and vexed with the operations of sinful corruptions; and they are these: partly to keep them humble and low in their own eyes; and partly to put them upon the use of all divine helps, whereby sin may be subdued and mortified ; and partly, that they may live upon Christ for the perfecting the work of sanctification; and partly, to wean them from things below, and to make them heart-sick of their absence from Christ, and to maintain in them bowels of compassion towards others that are subject to the same infirmities with them; and that they may distinguish between a state of grace and a state of glory, and that heaven may be more sweet to them in the close.” —Thomas Brooks, Precious Remedies against Satan’s Devices
