There are two things, among the many, that light does. It reveals the wrong and makes known that which is right. These two features of light are abundantly illustrated in the life of Christ. As to the first, when the Pharisees brought the woman to Christ, He said to them, "He that is without sin among you, let him first cast a stone at her," and "being convicted by their own conscience," they all slunk out of His holy presence (Jhn 8:7, 9). And as to Christ's making known the good, the right, the true, no one can prayerfully ponder John 3:16 without seeing the light of His love flashing out in its sevenfold perfection.
1. There is the red light of Christ's atonement in the given Son (Act 20:28).
2. There is the blue light of heaven in the "God gave" (2Cr 9:15).
3. There is the yellow light of heaven's glory in the "everlasting life" (Col 3:4).
4. There is the green light of faith in the "believe" (Jhn 3:36).
5. There is the orange light of safety in the "shall not perish" (Jhn 10:28).
6. There is the purple light of the eternal state in the "everlasting" (1Pe 1:3-4).
7. There is the white light of the effulgence of God in the "only begotten Son" (Hbr 1:5).
