God So Loved the World
The logic of salvation: love, giving, believing, and life.
Jesus speaks of the Father's love in sending the Son, presenting believing as the path from condemnation to everlasting life.
Scripture
16 For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life.
17 For God didn't send his Son into the world to judge the world, but that the world should be saved through him.
18 He who believes in him is not judged. He who doesn't believe has been judged already, because he has not believed in the name of the one and only Son of God.
19 This is the judgment, that the light has come into the world, and men loved the darkness rather than the light; for their works were evil.
20 For everyone who does evil hates the light, and doesn't come to the light, lest his works would be exposed.
21 But he who does the truth comes to the light, that his works may be revealed, that they have been done in God."
