What does it mean to be a saint according to the Bible?

In biblical terms, a saint refers to one who is sanctified or set apart for the glory of God. While they are called saints, it is essential to recognize that they are also vile sinners in need of grace, as highlighted in passages like Ephesians 2:1-3, which affirm that all are dead in sin. A saint’s standing before God is based on Christ’s atoning work, which means that despite their failings, they are redeemed and called by Him for a purpose. This dual identity—as both sinner and saint—emphasizes the grace of God in the life of believers.
