It requires understanding that you cant get from one verse-- and it'd be good, since you're interested, to read all of the New Testament to gain that understanding.
John 1:
1 In the beginning was the Word, and the Word was with God, and the Word was God;
2 this one was in the beginning with God;
3 all things through him did happen, and without him happened not even one thing that hath happened.
4 In him was life, and the life was the light of men,
5 and the light in the darkness did shine, and the darkness did not perceive it.
6 There came a man -- having been sent from God -- whose name is John,
7 this one came for testimony, that he might testify about the Light, that all might believe through him;
8 that one was not the Light, but -- that he might testify about the Light.
9 He was the true Light, which doth enlighten every man, coming to the world;
10 in the world he was, and the world through him was made, and the world did not know him:
11 to his own things he came, and his own people did not receive him;
12 but as many as did receive him to them he gave authority to become sons of God -- to those believing in his name,
13 who -- not of blood nor of a will of flesh, nor of a will of man but -- of God were begotten.
John 3:
16 for God did so love the world, that His Son -- the only begotten -- He gave, that every one who is believing in him may not perish, but may have life age-during.
17 For God did not send His Son to the world that he may judge the world, but that the world may be saved through him;
18 he who is believing in him is not judged, but he who is not believing hath been judged already, because he hath not believed in the name of the only begotten Son of God.
19 'And this is the judgment, that the light hath come to the world, and men did love the darkness rather than the light, for their works were evil;
20 for every one who is doing wicked things hateth the light, and doth not come unto the light, that his works may not be detected;
21 but he who is doing the truth doth come to the light, that his works may be manifested, that in God they are having been wrought.'
