Penance is our willingness to show that we want to be right with God and show sorrow for our sins through acts of penance.
What you’re talking about is temporal punishment due to sin. Confession does not inherently, nor automatically, wipe the punishments due to sin.
This is a very sticky topic, but to clean it all up, basically, the temporal punishments due to sin will be made known in your personal judgement and for all the heavenly elect to know in the general judgement (how the effects of your sins affected others and their salvation, stuff like that).
Here are some ways to reduce or eliminate temporal punishments due to sin [DISCLAIMER, again, punishment due to sin is between you and God]
- if you have offended someone, go to that person, apologize, make restitution, and try not to offend again (you broke their lamp, so you repaired the lamp, paid for the repair, or bought a new one).
- offer penance for the temporal remission of sin by decidedly solemn prayers, fasting, or almsgiving (you broke your friends lamp, they are so mad, they don’t even want to talk to you, so you offer some penance for being bad to your friend by either donating some money to a worthy cause, saying a rosary or a series of them, or do a bit of fasting, maybe skip a meal or two.
- there is always divine mercy sunday … where the indulgence permits the remission of all punishment due to sin, in your whole life, for everything, for anything, up to the point of your confession. look that one up, this one is probably for you!
Sure there are other ways, these are the basics that I use to help with sins. This is all murky ground, you’ll never know how your sacrifices are applied to your punishments, if at all, or if all of it … TRUST in the infinite MERCY that is God … do what you can that you know you can to remit the temporal punishment due to sin … but as we go through all this, we learn very quickly that it is soooooo much better to avoid the sin in the first place. And, in the end, if you’ve not paid enough for your temporal punishments, there’s always the final purification of Purgatory to release any and all worldly attachments and uncleanliness, so there is a safety net.
