What does the Bible say about the first resurrection?

The first resurrection refers to the spiritual awakening and regeneration that occurs in the heart of the believer when they hear the voice of Christ. As stated in John 5:25, 'the dead shall hear the voice of the Son of God, and they that hear shall live.' This emphasizes the sovereign act of God in bringing life to those who are spiritually dead due to sin. Regeneration is not a decision made by an individual but a miraculous work of God that enables them to believe in Christ and receive everlasting life. Essentially, it is the new birth that Jesus spoke about in John 3:3, which must occur for anyone to enter the Kingdom of God.
