Can an argument be won and should you even start the argument?

Each Day we face many challenges and at times we choose to argue our case.This weekend in Vayera reading Abraham faces three challenges. In the first one God wants to destroy Sodom and Gomorrah. Abraham does his best to argue passionatley to save people hi does not even know. Does he win this argument?
Next, his wife Sarah demands that Hagar and her son ( also the son of Abrahm) be sent away. Abraham chooses not to argue with Sara and does what his wife demands.  (Abraham does not argue).
Later, God instruct Abaraham to make the ultimate sacrifice and give up the son of Sarah, Isaac, at a certain location. Now again, Abarahm does not argue.
Dale Carnegie writes in his book: " How to win friends and influence people" an entire chapter in the section: "How to win people to your way of thinking " called- You can't win an argument.( page 109)

Did Abraham learn this earlier on in his first attempt to argue the case of the people of Sodom? Are there things worth standing up for? How do we stay committed to what we believe is right, at the same time not causing the other party to  turn away from us ? Can our business or personal life afford to have the results faced by Lot's wife's and become a pillar of salt just because we chose to make the wrong move and argue?

Going to the unknown- Ancient Ties to modern life

Many times Abram (A.k.A later in life as Abraham) took very large steps and made decisions that were monumental. The Midrash (Stories to help us in interpretation of the Biblical text) inform us of the time Abram decided to break every idol but one, that were in the possession of his father. At the time Abram did not know what would be the reaction of his father
When Abram was older he left his home, the surroundings that were familiar to him, and went again to the unknown. Many times in our lives we have to go and face the unknown.
Later in life Abram became Abraham, the father of many nations. Greatness and respect came his way because of the risks he took. These risks are based on trust.
Each day we face many unknowns. The thing we need to make sure is that we have someone who will be there to help guide us with our "leap of faith". Only when we are ready to believe in what we are doing, are we able to feel secure in our journey.
