How useful and necessary this fatherly chastening of God is for us cannot even be expressed. Consider how many spiritual infirmities are hidden in our heart, born with us in fleshly birth. What pride, anger, malice, envy, love of money, impurity, and other things are there!
The all-seeing eye of God sees all these infirmities. By bringing afflictions and misfortunes, as by a harsh medicine, He wishes to heal them, if we surrender ourselves to His will.
Every affliction and misfortune teaches us humility, patience, meekness, and every other good. Who, in sickness, will want to be malicious and take revenge? Who, in poverty, prison, or exile, will be proud?
Misfortune teaches one to humble oneself and endure everything. Misfortune is like a bridle by which fierce horses are restrained and tamed. Our nature grows fierce and as though rages, but by calamities and misfortunes, as by a bridle, it is restrained and tamed.
Although calamity and the affliction that befalls us are bitter for our flesh, they are healing for our soul. We are comforted and rejoice when a physician heals our infirm body, even if the healing comes through bitter and harsh medicine. We thank him and pay him a reward.
All the more should we rejoice and thank God from the heart when He heals our spiritual infirmities by afflictions and misfortunes.
