At one time or another, all of us have felt as if we were the only person in the world, totally alone in our struggles. In reality that has never been true of us, but Noah was one person who could actually claim such a grievance. Besides his wife and his three sons (and their wives), Noah had to stand alone against the world with only his faith in God to secure him.
There was only one way for Noah's ark to save him: he had to climb aboard. It required a step of faith. Dr. David Jeremiah describes the difference between knowing about God and knowing God well enough to trust His promises.
