Should Christians Pay Attention to Genealogies?
The genealogies leading to the Messiah, Jesus Christ, are vitally important as supportive proofs of his being qualified as God’s Messiah (Matthew 1:1-16; Luke 3:23-38). So we definitely do need them, and should pay attention to them.
Other Biblical genealogies are important for Biblical historical purposes, and we should be aware of them, but, these are not of great importance for Christians.
While there is nothing wrong with searching for one’s own family genealogy, there is also no requirement for a Christian to do so. This is one of those areas that is up to one’s own personal choice.
