My parents were 44 years of age when I was born.  They did not want another child as they already had three children, and were not anticipating diapers again.  I believed I was a mistake until I gave my life to the hands of Jesus Christ, and He showed me that I am not a mistake but of value.  Because of that experience I see value in each person.  I believe that is why I love John Maxwell as he teaches us to value all people.
