Did you know there's a gatekeeper who lives in our mouth? His job is to look at every word before it comes out and say, "This word is good, it can pass!" or "Whoa, this word will hurt someone, go back!"
The foolish child leaves the gate wide open. When they get angry, they say whatever pops into their head, and end up hurting the people they love most.
The wise child closes their mouth, takes a breath, and lets their brain think for just a moment. And when they finally speak, their voice is calm, and everyone listens, because they chose smart words. Jesus was like that: he always thought with love before speaking to people.
