Genealogy has become increasingly popular with the advent of modern technology that allows us to trace our DNA back through time. In the same way that we can see how the choices made by previous generations still impact our earthly lives today, we can also see the spiritual impact of those who have gone before us. It's not only important for us to live in obedience to God for our own benefit -- it also makes a difference to other believers both in the here and now, and in the generations to come.
