Finding a dvar Torah topic - A Story

I remember the dvar Toah writing process as my own children became bar/bat mitzvah. My oldest son had the portion Vayera in the book of Bereshit(Genesis). I remember people saying that all the parashiot in Genesis were easy because they all have great stories and it is so easy to find something that relates to our lives. I still believe this to be true, but it is still hard because there are so many themes and ideas that it can be hard to narrow it down. The portion Vayera includes the story of the near sacrifice of Isaac by his father Abraham. This is a difficult text and I remember that the idea of writing a dvar Torah about it made my son very nervous. To solve things, I told him that lots of people (more that we know!) have commented on this and he could choose something else in the parasha. He ended up writing a beautiful speech on the places in the parasha where people argued with God and why they might have done that. Most notably, he talked about Abraham's arguing with God regarding the destruction of Sodom. He connected it to his own personal expereince of arguing with teachers and other authority figures. What a perfect theme for a budding adolescent!
