How do we know if a person is truly saved?

Salvation is rooted in God's grace and is granted through God's initiative. As seen in John 1:13, a person is born not of their own will but by God's divine will. A true believer will exhibit signs of faith and repentance as a manifestation of the new birth given by the Holy Spirit. The Spirit works within believers, enabling them to repent and believe, which demonstrates that their salvation is effective and genuine, even before they fully understand or articulate their faith. Hence, the assurance of salvation does not depend on our actions but on God's sovereign grace and the evidence of a transformed life.
