Courageous is a very good movie, with great insight on what makes a father and how generation after generation, has suffered from their lack. But it's tough to watch.
I know loosing a child is the hardest thing a person will experience. If you disagree, ask yourself why God gave his son to atone for our sins. We're pretty bad people, so it was going to take a pretty big sacrifice. He didn't send his mother, aunt Betsy or cousin Burt. He sent His heart. Our children are our hearts. Though I didn't know what I was saying at the time, I recall telling the doctor, who had delivered the terrible news, Lauren could not be dead. She was my heart and my heart was still beating.
God knew, even if you had never had a child of your own, you would understand the depth of his love by his sacrifice. You had once been a child who either loved a father or longed for one. He knows our hearts, because we are His heart.
