If you believe in a Divine Providence which determines the earthly fate of everyone and the way by which he is to be saved, you must also believe that the disposition of your life is the most suitable for you in working out your salvation.
As too many sticks often choke a fire and put it out, while making a lot of smoke, so excessive sorrow often makes the soul smoky and dark, and dries the stream of tears.
Without sorrows there is no salvation. On the other hand, the Kingdom of God awaits those who have patiently endured. And all the glory of the world is nothing in comparison.
Most people desire and seek after prosperity in this life, and they strive to avoid sorrows. While that seems very good and pleasant, constant prosperity and good fortune do a person harm. He falls into a variety of passions and sins, and angers the Lord, while those who live a life of sorrow come closer to the Lord and more readily attain unto salvation, for the Lord called the life of happiness the broad path. The wide gates and the broad way lead to destruction, and many there be who take that way (Matthew 7:13). It is the narrow way and the strait gate which lead to life eternal, and few there be who find it (Matthew 7:14). Thus, according to His love for us, seeing the possible benefit [of sorrows] to those who are worthy, the Lord moves many off the broad road and puts them on the narrow, sorrowful path, so that in [their] patient endurance of sickness and sorrow, He might effect their salvation and grant them life eternal.
Nothing that happens to us is contrary to the will of Providence, and everything that is sent us by God is for our good and the salvation of our soul. Even if it does not seem helpful at the moment, we shall understand later on that it was willed so by God, and that it is not what we ourselves wish that is always useful to us. God sends trials out of his Mercy, so that after we have suffered, we may be crowned by Him. Without temptation it is impossible to receive a crown. This is why we should thank God for these sufferings, as out Benefactor and Savior.
