How do we know that Christ is the true light of the world?

In John 1:1-14, we learn that Jesus, referred to as the Word, was both with God and was God. This revelation confirms that Christ embodies the light that shines in the darkness, defeating the ignorance and blindness of sin. The verse states that 'the light shineth in darkness; and the darkness comprehended it not' (John 1:5), emphasizing the rejection of His truth by those in darkness. Therefore, recognizing Christ as the true light involves not only understanding His divine nature but also experiencing His illuminating work in our hearts, as He draws us to Himself.
