How do we know we cannot commit sin if we are born of God?

The assurance that one cannot commit sin if truly born of God comes from 1 John 3:9, which states, 'He cannot sin because he is born of God.' This assertion is founded on the transformational work of the Holy Spirit that implants a new divine nature into believers. This divine nature, or 'seed,' signifies a complete inability to commit sin as it is inherently righteous and aligned with God's character. While the outer man, influenced by the flesh, continues to sin, the inner spiritual man, born of God, is liberated from sin's condemnation. Hence, this theological distinction ensures that the acts of sin do not define a regenerate person, but rather affirm their ongoing spiritual struggle with the flesh.
