“Afflictions quicken us to prayer.
It is a pity it should be so; but experience testifies, that a long course of ease and prosperity, without painful changes—has an unhappy tendency to make us cold and formal in our secret worship.
But troubles rouse our spirits, and constrain us to call upon the Lord in good earnest—when we feel a need of that help which we only can have from His Almighty arm.
Afflictions are useful, and in a degree necessary, to keep alive in us—a conviction of the vanity and unsatisfying nature of the present world, and all its enjoyments; to remind us that this world is not our rest, and to call our thoughts upwards, where our true treasure is, and where our heart ought to be.
When things go on much to our wish, our hearts are too prone to say, ‘It is good to be here!'”
