What does the Bible say about the evidence of being born of God?

The evidence of the new birth is clearly outlined in 1 John 5:1, which says, "Whosoever believeth that Jesus is the Christ is born of God." This indicates that true faith in Jesus Christ, recognizing Him as the Messiah, is the foundational evidence of one's relationship with God. The Apostle John emphasizes that belief in Christ’s identity as the anointed one fulfills all Old Testament prophecies, marking it as central to being born again. Without this belief, one cannot regard themselves as a child of God.
