John 1:5

“And the light shineth in darkness, etc.] Which, through sin, came upon the minds of men; who are naturally in the dark about the nature and perfections of God; about sin, and the consequences of it; about Christ, and salvation by him; about the Spirit of God, and his work upon the soul; and about the Scriptures of truth, and the doctrines of the Gospel. Man was created a knowing creature, but, not content with his knowledge, sins, and is banished from the presence of God, the fountain of light; which brought a darkness on him, and his posterity, and which is increased in them by personal iniquity, and in which Satan, the god of this world, has an hand; and sometimes they are left to judicial…”

“shineth in darkness, &c.--in this dark, fallen world, or in mankind "sitting in darkness and the shadow of death," with no ability to find the way either of truth or of holiness. In this thick darkness, and consequent intellectual and moral obliquity, "the light of the Word" shineth--by all the rays whether of natural or revealed teaching which men (apart from the Incarnation of the Word) are favored with. the darkness comprehended it not--did not take it in, a brief summary of the effect of all the strivings of this unincarnate Word throughout this wide world from the beginning, and a hint of the necessity of His putting on flesh, if any recovery of men was to be effected (Co1 1:21).”

“The light shineth in darkness - Darkness, in the Bible, commonly denotes ignorance, guilt, or misery. See Isaiah 9:1-2; Matthew 4:16; Acts 26:18; Ephesians 5:8, Ephesians 5:11; Romans 13:12. It refers here to a wicked and ignorant people. When it is said that “the light shineth in darkness,” it is meant that the Lord Jesus came to teach an ignorant, benighted, and wicked world. This has always been the case. It was so when he sent his prophets; so during his own ministry; and so in every age since. His efforts to enlighten and save men have been like light struggling to penetrate a thick, dense cloud; and though a few rays may pierce the gloom, yet the great mass is still an impenetrable…”

“And the light shineth in darkness - Shines even on fallen man; but the darkness - Dark, sinful man, perceiveth it not. John 1:6”

“1:5 the darkness can never extinguish it: Or the darkness has not understood it; literally the darkness cannot grasp it. The Greek word katalambanō (“grasp”) can mean either “understand” or “be hostile”; in John’s Gospel, it means hostility. The darkness would try to destroy Jesus (the light), but it would fail. The light would successfully bring salvation to the world.”
