A just view of afflicting incidents is altogether necessary to a Christian deportment under them; and that view is to be obtained only by faith, not by sense; for it is the light of the world alone that represents them justly, discovering in them the work of God, and consequently, designs becoming the Divine perfections. When they are perceived by the eye of faith, and duly considered, we have a just view of afflicting incidents, fitted to quell the turbulent motions of corrupt affections under dismal outward appearances.
