What is the significance of holiness for Christians?

Holiness in the Christian context signifies a state of being that is set apart for God. It is not a mere checklist of actions but a transformation of one's nature through the sanctifying work of the Holy Spirit. Hebrews 12:14 exhorts believers to pursue holiness, as without it no one will see the Lord. This holiness is essential for true fellowship with God and is a reflection of God's own nature. Believers are called to be holy as He is holy, indicating that sanctification is both an ongoing process and a fundamental aspect of their identity in Christ, who is their holiness.
