How does light shine in a believer's heart?

In 2 Corinthians 4:6, Paul states that 'For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.' This verse metaphorically depicts the moment of conversion, where God's power brings illumination to the believer's heart, leading to spiritual awakening and understanding. The work of the Holy Spirit is vital in this process as He enables a person to recognize their sin and need for Christ. This 'light' reveals the truth of the gospel, transforming a believer’s life and setting them on the path of righteousness. Thus, the shining of light in the heart signifies the heart of the gospel's transformative power in an individual's life.
