The Saints on Suffering.......

As iron is fashioned by fire and on the anvil, so in the fire of suffering and under the weight of trials, our souls receive that form which our Lord desires them to have.
--St. Madeline Sophie Barat

If God gives you an abundant harvest of trials, it is a sign of great holiness which He desires you to attain. Do you want to become a great saint? Ask God to send you many sufferings. The flame of Divine Love never rises higher than when fed with the wood of the Cross, which the infinite charity of the Savior used to finish His sacrifice. All the pleasures of the world are nothing compared with the sweetness found in the gall and vinegar offered to Jesus Christ. That is, hard and painful things endured for Jesus Christ and with Jesus Christ.
--Saint Ignatius of Loyola

'When it is all over you will not regret having suffered; rather you will regret having suffered so little, and suffered that little so badly.'
--St. Sebastian Valfre

"I do not desire to die soon, because in Heaven there is no suffering. I desire to live a long time because I yearn to suffer much for the love of my Spouse."
--St. Mary Magdalene de Pazzi

You will be consoled according to the greatness of your sorrow and affliction; the greater the suffering, the greater will be the reward. 
--St. Mary Magdalen de'Pazzi

For my heart is always with Him, day and night it thinks unceasingly of its heavenly and divine Friend, to whom it wants to prove its affection. Also within it arises this desire: not to die, but to suffer long, to suffer for God, to give Him its life while praying for poor sinners.
--Bl Elizabeth of the Trinity
