Our holiness is established through God's choice, Christ's sacrifice, and the regeneration by the Holy Spirit.
We know we are holy in God's sight primarily through the biblical teaching that establishes holiness as a result of God's sovereign election. Ephesians 1:4 states that God chose us in Him before the foundation of the world to be holy. Furthermore, Hebrews 10:10 clarifies that it is by Christ's offering that we are sanctified and thus made holy. Additionally, this holiness is affirmed by the indwelling of the Holy Spirit, which regenerates us and grants us a new nature (2 Thessalonians 2:13). Therefore, our standing as 'holy brethren' is grounded not in our performance, but in the completed work of Jesus Christ and God's eternal purpose.
