How do we know that persevering in faith is true?

The doctrine of perseverance is rooted in the transformative work of God in His people. According to 1 John 3:9, those who are truly born of God do not commit sin, indicating that they cannot turn away from their faith in Christ. The seed of Christ remains in the believer, which empowers them to persevere in faith. This assurance is echoed in the context of the epistle where John comforts believers by affirming that they will not depart from the truth, as it is God who keeps them. The ongoing presence of faith in their lives serves as evidence of their new birth and eternal security.
