What does it mean to be born again in the Spirit?

To be born again signifies a profound spiritual transformation wrought by the Holy Spirit, as illustrated in John 3. This regeneration imparts new life to the believer, changing their heart, mind, and affections towards God. The Holy Spirit convicts individuals of sin, leading them to repentance and faith in Christ. As a result, believers are endowed with a new nature that seeks holiness, turning their lives away from sin and towards the righteousness of God. This process encapsulates not just a change of behavior, but an entire reorientation of life under Christ's lordship, ensuring that they cannot ultimately fall away from the faith because of the sustaining power of the Spirit.
