Trust you're doing well @raqueluchap.
It's true that forgiveness is very important not only because God commanded us to do it.He say in the book of Mark 11:25 - And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven will forgive you your sins”
It is something we ask God for daily, so it is a command that benefits not only the one who forgives but also the one who is forgiven.in all, forgiveness is the key.
Good luck!
