Treasury of Scripture Knowledge
So, Jesus spoke to them again [i.e., to the Jewish authorities. See 7:45], saying, "I am the light of the world. The person who becomes my follower will never live in [spiritual] darkness, but have the light of [i.e., for his] life [i.e., followers of Jesus will not live in error and sin but in truth and righteousness]."
While I am in the world I am the light of the world."
For the Lord commanded us to do this by saying, 'I have appointed you to be a light to the [unconverted] Gentiles, so that you should be [the occasion] for [bringing] salvation to the farthest corner of the earth.' "
2 Corinthians 4:6
For God, who said [Gen. 1:3], "Light will shine out of darkness," has [also] shone in our hearts to provide [us with] the light of the knowledge of God's splendor [as it shines] on the face of Christ. [Note: This allusion to "splendor shining on Christ's face" may be a continuation of the analogy used in 3:13].
2 Timothy 1:10
But, it has [only] now been made known to us by the appearance of our Savior Christ Jesus, who has put an end to death and brought [never ending] life and incorruption [i.e., immortality] to light through the Gospel [message],
Then He opened their minds [miraculously ?] so they would understand the Scriptures.
