I don't think that most people grasp the magnitude of what happened 2000 years ago. Most people were living in spiritual darkness and then with the birth of Christ it was as though someone turned on the light switch! The light had come!
Those who had grown accustomed to the darkness and loved the darkness hated the light and wanted to turn off the light. Just like then, there are many people today who wish that they could turn off the light of Jesus and also those that reflect His light. But those who reject the light stand condemned and unless they come to saving faith in Jesus Christ, will remain in darkness forever!
16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. 17 For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. 18 “He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. 21 But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.” (John 3:16-21)
