Among Christians there's an age-old joke about reading your Bible and getting to the genealogies and we have two problems with them.

First of all they seem boring to us and secondly we can't pronounce half the names and so we might wonder why are they even there? Well the genealogies in Scripture serve one primary purpose. They serve multiple purposes but the one primary purpose is that they are proofs of the faithfulness of God to his own promises.

For example the most famous genealogy in the Bible, the most important one, I might even say, is the genealogy of Jesus Christ. And the genealogy of Jesus Christ, one found in Matthew, one found in Luke, prove that Jesus is exactly who God said he would be, going all the way back to Abraham, in the case of the genealogy in Matthew, and going all the way back to Adam and God himself, in the case of the genealogy in Luke.

So genealogies are there to give you faith that God keeps his promises.
