Why can those born of God not sin?

The reason those who are born of God cannot sin lies in the new nature bestowed upon them through regeneration. According to 1 John 3:9, 'Whosoever is born of God doth not commit sin; for His seed remaineth in him.' This indicates that the divine nature imparted by God is incapable of sinning. However, believers still contend with their old, sinful nature, which creates an internal conflict. This division of natures is crucial for understanding the believer's experience and relationship with sin.
