Grace and good works affect others not only in natural, but in mystical ways
Reading Exodus 20, the Torah, again:
Exodus 20:5-6
“…I am the Lord thy God, mighty, jealous, visiting the iniquity of the fathers upon the children, unto the third and fourth generation of them that hate me. And shewing mercy unto thousands to them that love me, and keep my commandments.”
The good we do, by the grace of Christ, ripples out into the universe and builds up His Body:
Colossians 1:23-24
“If so ye continue in the faith, grounded and settled, and immoveable from the hope of the gospel which you have heard, which is preached in all the creation that is under heaven: whereof I Paul am made a minister. Who now rejoice in my sufferings for you and fill up those things that are wanting of the sufferings of Christ, in my flesh, for His body, which is the church…”
When we cooperate with grace — when we pray, give alms, fast, offer up our sufferings, etc. — we literally strengthen the Body of Christ in a mystical way! Christ Himself and all the Saints of 2,000 years (by the grace of Christ) have built up His Mystical Body (the Catholic Church) and laid up a “treasury of merit” or “spiritual treasury,” as it is also called. In the same way we or others detract from the Body of Christ through sin, we and others add to this treasury — and receive the fruits thereof when we receive an indulgence, for we are one in the Body of Christ:
Romans 7:5
“We being many, are one body in Christ, and every one, members one of another.”
And read once again I Corinthians 12:26:
“And if one member suffer any thing, all the members suffer with it: or if one member glory, all the members rejoice with it.”
The Church was given the power to bind and loose
To Peter was given the Keys to the Kingdom (Matthew 16) and the power of binding and loosing (forbidding/permitting, condemning/acquitting). In exercising this power of the Keys, the Church has the authority to determine certain practices which help us to to benefit from the treasury of merit and alleviate the temporal effects of sins we’ve confessed and are already forgiven for. This is an indulgence.
That the Church was given the power to forgive the eternal effects of sin through the Sacrament of Penance makes it easier to understand how the Church also has the power to alleviate the lesser, temporal effects of sin. The Church whose priests were given the authority by Christ to forgive the guilt of sin and thereby, by the Blood of Christ, eliminate the eternal punishments for sin, surely also has the authority to pardon the temporal punishments of sin.

Summa Catechetica, "Neque enim quaero intelligere ut credam, sed credo ut intelligam." – St Anselm, "“Si comprehendus, non est Deus.” -St Augustine, "Let your religion be less of a theory, and more of a love affair." -G.K. Chesterton, “When we pray we speak to God; but when we read, God speaks to us.” -St Jerome, "As the reading of bad books fills the mind with worldly and poisonous sentiments; so, on the other hand, the reading of pious works fills the soul with holy thoughts and good desires." -St. Alphonsus Liguori, "And above all, be on your guard not to want to get anything done by force, because God has given free will to everyone and wants to force no one, but only proposes, invites and counsels." –St. Angela Merici, “Yet such are the pity and compassion of this Lord of ours, so desirous is He that we should seek Him and enjoy His company, that in one way or another He never ceases calling us to Him . . . God here speaks to souls through words uttered by pious people, by sermons or good books, and in many other such ways.” —St. Teresa of Avila, "I want a laity, not arrogant, not rash in speech, not disputatious, but men and women who know their religion, who enter into it, who know just where they stand, who know what they hold and what they do not, and who know their creed so well that they can give an account of it, who know so much of history that they can defend it. I want an intelligent, well-instructed laity… I wish you to enlarge your knowledge, to cultivate your reason, to get an insight into the relation of truth to truth, to learn to view things as they are, to understand how faith and reason stand to each other, what are the bases and principles of Catholicism, and where lie the main inconsistences and absurdities of the Protestant theory.” (St. John Henry Newman, “Duties of Catholics Towards the Protestant View,” Lectures on the Present Position of Catholics in England), "We cannot always have access to a spiritual Father for counsel in our actions and in our doubts, but reading will abundantly supply his place by giving us directions to escape the illusions of the devil and of our own self-love, and at the same time to submit to the divine will.” —St. Alphonsus Ligouri, "The harm that comes to souls from the lack of reading holy books makes me shudder . . . What power spiritual reading has to lead to a change of course, and to make even worldly people enter into the way of perfection." –St. Padre Pio, "Screens may grab our attention, but books change our lives!" – Word on Fire, "Reading has made many saints!" -St Josemaría Escrivá, "Do you pray? You speak to the Bridegroom. Do you read? He speaks to you." —St. Jerome, from his Letter 22 to Eustochium, "Encounter, not confrontation; attraction, not promotion; dialogue, not debate." -cf Pope Francis, "God here speaks to souls through…good books“ – St Teresa of Avila, Interior Castle, "You will not see anyone who is really striving after his advancement who is not given to spiritual reading. And as to him who neglects it, the fact will soon be observed by his progress.” -St Athanasius, "To convert someone, go and take them by the hand and guide them." -St Thomas Aquinas, OP. 1 saint ruins ALL the cynicism in Hell & on Earth. “When we pray we talk to God; when we read God talks to us…All spiritual growth comes from reading and reflection.” -St Isidore of Seville, “Also in some meditations today I earnestly asked our Lord to watch over my compositions that they might do me no harm through the enmity or imprudence of any man or my own; that He would have them as His own and employ or not employ them as He should see fit. And this I believe is heard.” -GM Hopkins, SJ, "Only God knows the good that can come about by reading one good Catholic book." — St. John Bosco, "Why don't you try explaining it to them?" – cf St Peter Canisius, SJ, Doctor of the Church, Doctor of the Catechism, "Already I was coming to appreciate that often apologetics consists of offering theological eye glasses of varying prescriptions to an inquirer. Only one prescription will give him clear sight; all the others will give him at best indistinct sight. What you want him to see—some particular truth of the Faith—will remain fuzzy to him until you come across theological eye glasses that precisely compensate for his particular defect of vision." -Karl Keating, "The more perfectly we know God, the more perfectly we love Him." -St Thomas Aquinas, OP, ST, I-II,67,6 ad 3, “But always when I was without a book, my soul would at once become disturbed, and my thoughts wandered." —St. Teresa of Avila, "Let those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me." –St. Augustine, "Without good books and spiritual reading, it will be morally impossible to save our souls." —St. Alphonsus Liguori "Never read books you aren't sure about. . . even supposing that these bad books are very well written from a literary point of view. Let me ask you this: Would you drink something you knew was poisoned just because it was offered to you in a golden cup?" -St. John Bosco " To teach in order to lead others to faith is the task of every preacher and of each believer." —St. Thomas Aquinas, OP. "Prayer purifies us, reading instructs us. Both are good when both are possible. Otherwise, prayer is better than reading." –St. Isidore of Seville “The aid of spiritual books is for you a necessity.… You, who are in the midst of battle, must protect yourself with the buckler of holy thoughts drawn from good books.” -St. John Chrysostom
