You, who have shown me great and severe troubles, shall revive me again, and bring me up again from the depths of the Earth. You shall increase my greatness, and comfort me on every side – Psalm 71:20-21 NKJV.
Many can agree that God has shown us "great and severe troubles," just as the psalmist writes of. The Lord has excellent reasons for allowing distresses to come our way. They may arrive for correction, sanctification, enlightenment, or a number of other motives.
