What does being 'born again' mean in the Christian faith?

In Christian theology, being 'born again' signifies a profound transformation initiated by the Holy Spirit, leading to spiritual regeneration. It is necessary for entering the kingdom of God, as stated in John 3:3. This rebirth does not reflect a physical change but rather a spiritual awakening that enables individuals to perceive and respond to the gospel. By God's sovereign choice, the believer is given a new nature, characterized by a desire to follow Christ and a capacity to believe in Him for salvation. This process underscores God's initiative in our salvation, confirming that it is not by our will but by His grace alone.
