A closing argument is a statement or small speech that sums up an argument, point, or statement. It highlights the most valid points and is meant to make you feel something: empowered, guilty, impassioned, sympathy, or something else. It is based on facts and evidence, but if you are not able to make the audience feel what you need them to feel, then you did not make your point.
Job was on his closing argument with his last appeal to society (his friends). He points out how easy it is to miss the good things in life until they are gone. However, how you handle the hard times is what defines you. Christian's are held at a higher standard because the world is watching and wanting you to fail. It is a lot of pressure, so we have to take the focus off the world and place it on the relationship with God.
Job held himself together very well because he knew he was right and never doubted it. He endured the ridicule even if he was angry. He was beginning to understand a hard truth of life and was trying to get his friends to understand too. Just because you live a "good life" does not mean that you will reap the rewards in life. Good things doesn't always happen to good people. Just like it is not a set rule that bad things happen to bad people. Job looked at himself and could not even recognize himself, but he knew he lived a righteous life.
God allows darkness into the world. He will remove it eventually, but this is the world that everyone has lived in. There is the equalizer of life. No one lives without experiencing suffering, pain, loss, temptation, failure, and more things that Satan brought into this world. The stories may vary, but we have all been hurt by life. Instead of focusing on what makes us different, maybe we should look at what unifies us and try to make it better for everyone. Job was saying instead of hurting each other more, try to find empathy. Try to relate instead of judge.
