The same way we that we as individuals sin against God and we need to repent, a group of people can also sin and need repentance. ‭‭But people within that group must take responsibility and repent.

2 Chronicles‬ ‭7‬:‭14‬ ‭NKJV‬ says “if My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land.”
