Holy Souls in Purgatory, is there anything you regret when you think of your life on earth? I deeply regret my neglect of acts of mortification. How easy they would have been on earth, but how difficult they are now in Purgatory. Here the smallest suffering is more poignant than the most cruel torments on earth. In the world it meant only patience and resignation in the hardships and adversities of my life; it meant only giving from my surplus to the poor, and devoting myself to works of atonement; it meant only gaining indulgences and performing works of piety. Nothing could have been easier, and my Purgatory would have been shortened considerably. If God would but grant me the grace to exchange the years during which I must still remain in this place of sorrow for as many years of life on earth! No commands would be too severe for me; no pains could frighten me; the most difficult works of penance would be sweet and give me comfort at the thought of this consuming fire. You who now smart under the insignificant trials and hardships of this life! You who now earn your daily bread by the sweat of your brow, rejoice! The smallest suffering endured in the spirit of atonement and offered to the Sacred Heart in the spirit of expiation, will save you from a long and painful Purgatory.
Suffering can't pay for sins.
What suffering here in this life can do....
Romans 5:1-5 Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. 2 Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God. 3 Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, 4 and endurance produces character, and character produces hope, 5 and hope does not put us to shame, because God's love has been poured into our hearts through the Holy Spirit who has been given to us.
2 Corinthians 1:3-7 Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, 4 who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God. 5 For as we share abundantly in Christ's sufferings, so through Christ we share abundantly in comfort too. 6 If we are afflicted, it is for your comfort and salvation; and if we are comforted, it is for your comfort, which you experience when you patiently endure the same sufferings that we suffer. 7 Our hope for you is unshaken, for we know that as you share in our sufferings, you will also share in our comfort.
Hebrews 2:18 For because he himself has suffered when tempted, he is able to help those who are being tempted.
Hebrews 5:8 Although he [Jesus] was a son, he learned obedience through what he suffered.
