What does the Bible say about the new birth and salvation?

The new birth, highlighted in John 3, is a vital aspect of salvation, which is entirely of God's grace and initiative. This regeneration is essential for individuals to see and enter the kingdom of God. The Scriptures tell us that human beings, due to their fallen nature, are incapable of choosing God without divine intervention. The Holy Spirit must regenerate the hearts of the elect, leading to repentance and faith. Ephesians 2:4-5 asserts that even when we were dead in transgressions, God made us alive in Christ, showcasing His rich mercy and love. Therefore, salvation is wholly a work of God, from beginning to end.
