Why is pursuing holiness important for Christians?

Pursuing holiness is essential for Christians as it manifests their new identity in Christ and demonstrates obedience to God's call. In Romans 12:1-2, Paul urges believers to present their bodies as living sacrifices, which is their reasonable service in light of God's mercies. This pursuit is not merely external but involves an inward transformation of the mind and spirit, enabling Christians to engage in good works and reflect the character of Christ. Holiness sets believers apart from the world, allowing them to fulfill God’s purposes and glorify Him through their lives.
