What does it mean to be a saint in Christ Jesus?

The term 'saint' refers to those who are sanctified in Christ Jesus, meaning they have been set apart by God for His purposes. In Philippians 1:1, Paul addresses 'all the saints in Christ Jesus,' indicating that all believers are called to be holy and to live lives that reflect Christ’s character. This identity as saints is rooted in God's grace, which enables us to pursue holiness and to be conformed to the image of His Son. As such, saints serve God and each other within the church, contributing to the collective witness of the Christian faith in the world.
