For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
As great as this verse is, and it is, the next few verses are such a great concise summary of this Christian life - that is for the followers of 'The Way'.
17 God did not send his Son into the world to condemn its people. He sent him to save them! 18 No one who has faith in God’s Son will be condemned. But everyone who doesn’t have faith in him has already been condemned for not having faith in God’s only Son.
19 The light has come into the world, and people who do evil things are judged guilty because they love the dark more than the light. 20 People who do evil hate the light and won’t come to the light, because it clearly shows what they have done. 21 But everyone who lives by the truth will come to the light, because they want others to know that God is really the one doing what they do. John 3.17-21 CEV
