Im Sorry - Vayikra

Many things we do in life may be big mistakes and things wrong, my question is. How do we repent? How do we fix what we did wrong? The answer i would think would be given is to bring a korbon if its spiritually bad and change to do something the opposite if its just something you did in your day to day life.
In this weeks parsha the commentary talks about my question it also gives me another question. In this century, how do i bring a korbon? Now i can answer my 2 questions fully.
In this day in age as much as we really want to have the bais hamikdash we dont have it yet, So we have to figure out a way to do what we need without actually physically bringing a korbon. The rambam brings down that if you learn the halachos of karbonos its like actually bringing one. We see here that everything can always be attoned for and we can always be forgiven. Lets hope that by the time pesach comes we are already forgiven and ready to go in yerushaliam celabrating my birthday with mashiach.
Moshiach now
Good shabbos
All the best
