What does the Bible say about how a person becomes a saint?

According to Ephesians 1:1-2, every believer is considered a saint. This status is not based on human merit or actions, but rather wholly upon the will of God. The Father chose a people for salvation before the foundation of the world, making them holy and without blame in Christ (Ephesians 1:4). It is also through faith in Jesus Christ that a person becomes a saint; believing in Him grants holiness and assurance. Additionally, it is by God’s grace, which is the unearned favor from Him, that believers are saved, emphasizing that salvation is not a product of human effort but solely a divine act.
