Why is the title 'firstborn' important for Christians?

The title of 'firstborn' is significant for Christians as it conveys the uniqueness and authority of Christ in the context of redemption and inheritance. In Colossians 1:18, it's stated that Christ is the head of the body, the church, and the firstborn from the dead, indicating His superiority and the chief role He plays in the resurrection and eternal life of His followers. Furthermore, being called the firstborn assures believers of their adopted status as children of God, granting them the same rights to inheritance through Christ. The honor of the firstborn reflects not only Christ's supremacy as the Savior but also highlights the corporate nature of salvation, where believers are included in the family of God as co-heirs with Him.
