My dear brothers and sisters in Christ, in our readings at Holy Mass, we are presented with a stark contrast between the acceptable offering to God and the destructive power of anger and resentment. In the first reading, we see Cain's jealousy and anger towards his brother Abel, which ultimately leads to the first recorded murder in human history. The story of Cain and Abel serves as a reminder that our actions have consequences, and that harboring anger and resentment can lead us down a path of destruction.
