In James 5, Jesus’ brother talks about the corruption, exploitation and, ultimately, the murder of the innocent by which some of the rich in that day were characterized. That was not just an example of boys being boys. It was considered evil. “The cries of the harvesters have reached the ears of the Lord Almighty.”
Speak for those who have no voice. Be a champion for the downtrodden (Proverbs 31:8). Do not promote violence, but promote peace (Matthew 5:9). How about a new saying: Boys will be like Jesus.

Thank you for this! I have 3 boys and hear this a lot!
