How do we know being born again is true?

The truth of being born again can be observed through its effects on an individual's life. In 2 Corinthians 5:17, Paul states, 'Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.' This change is not superficial but represents a spiritual awakening that shifts one's desires from sin to a longing for righteousness and a relationship with God. Furthermore, the presence of the Holy Spirit, which grants believers new affections and hunger for God's Word, serves as additional confirmation of their rebirth. As believers begin to feel satisfaction in worship and develop a deepening relationship with Christ, it underscores the reality of their spiritual rebirth.
