I invited the person who was going to knock my teeth out to go on a camping trip with my family. After school, in the church parking lot, we circled each other with the third guy egging us on. It didn't matter much. He was bigger than both of us put together. A kind word turneth away wrath.
Kindness can be as simple as saying the right thing at the right time.
Just because something is true does not mean that now is the best time to say it. Even Jesus knew better than to tell His disciples everything. He knew that they would not be able to bear such knowledge at that time. There is a false goodness that we all fall for. Goodness developed to meet other s expectations.
