Why is it important to follow Christ as the light?

Following Christ means embracing His illuminating truth, which leads to salvation and eternal life. John 3:19 explains the human inclination to love darkness over light due to the evil of deeds. However, those who are drawn to the light are enabled by the Holy Spirit to recognize their sinfulness and seek salvation in Christ. This transformation is essential as it demonstrates the work of grace in a believer's life, highlighting the importance of Christ as the sole source of hope and righteousness in a dark world.
