Bible Old Testament being relevant in today’s world – family dynamics

Some people comment that the Bible - Old Testament contains ancient stories that have little to do with today’s world. However, if one read each story and the entire OT, one would find it very much related to the family dynamics of today’s world: the chaos in David’s family and his clinging onto God, the twin brothers Esau and Jacob along with the favouritism being and the scheme-of-a-woman doing of their mother Rebekah plus Isaac’s self-satisfying (e.g. gluttony) lifestyle… etc.
