Biblical genealogies today

At Evangel Justin Taylor interviews Gerald Bray on how to apply biblical genealogies today. Some of the answers are worth reading. Here's an example:

What do they tell us about ourselves?

They say that most of us are nobodies from the world’s point of view. We live and die in a long chain of humanity but there is not much that anyone will remember of us as individuals. At the same time, without us, future generations will not be born and the legacy of the past will not be preserved. We are part of a great cloud of witnesses, a long chain of faithful people who have lived for God in the place where he put them. Even if we know little about them we owe them a great debt of gratitude for their loyalty and perseverance when they had little or nothing to gain from it or to show for it.

Good points, along with others in the whole post.
