What does it mean to be born again according to Scripture?

Being born again, as described in John 3:3, indicates a spiritual rebirth through the Holy Spirit. This regeneration alters one’s nature, allowing the individual to respond in faith to the gospel of Christ. In Acts 13, the mention of belief highlights the necessity of God's action in making a person willing to come to Him. It underscores the truth that humanity, in its natural state, is dead in trespasses and sins, requiring divine intervention for salvation. This transformation is central to sovereign grace theology, emphasizing that it is entirely a work of God’s grace, not from human effort.
