How do we know we are called to be holy?

The calling to holiness is a central theme in the New Testament, especially articulated in Hebrews 3:1. Every believer, referred to as 'holy brethren,' is part of a divine election that marks them as holy because of Christ's redemptive work. This holiness is not based on personal merit but is granted through God's grace. Ephesians 1:4-5 emphasizes this by stating that God chose us in Christ before the foundation of the world so that we would be holy and blameless in His sight. Understanding this calling helps believers live in a manner that reflects their identity as those set apart for God’s purpose.
