John 1:9 That was the true Light which gives light to every man coming into the world. Everyman receives light
Ephesians 5:13 But everything exposed by the light becomes visible—and everything that is illuminated becomes a light. Everyman is exposed by the light to the truth.
One must see their sin in order to repent of it and the bible says in Acts 17:30-31 Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained.
It is mans refusal to do so because he loves darkness more than light that damns him. John 3:19 1And this is the verdict, that the light came into the world, but people preferred darkness to light, because their works were evil. 2For everyone who does wicked things hates the light and does not come toward the light, so that his works might not be exposed.
