How do we know sainthood is true?

The truth of sainthood is grounded in the biblical understanding of God’s eternal covenant with His people. As referenced in Psalm 50 and validated in New Testament writings, being a saint is inherently linked to God's choice and Christ’s redemptive work. John 6:37 emphasizes that all that the Father gives to Jesus will come to Him, assuring us of the validity of our sainthood. Additionally, the doctrine of justification, supported in Romans and 1 Peter, confirms that we are made righteous before God solely by the imputed righteousness of Christ, thereby establishing the truth of our saintly status.
