What are the subtopics of God's love in John 3:16-18?

1. The extent of God's love: "For God so loved the world"
2. The demonstration of God's love: "that he gave his one and only Son"
3. The purpose of God's love: "that whoever believes in him shall not perish but have eternal life"
4. The response to God's love: "whoever believes in him is not condemned"

- God's love is unconditional: "For God so loved the world..." (v. 16)
- God's love is for all people: "...that He gave His only begotten Son..." (v. 16)
- God's love is sacrificial: "...that whoever believes in Him should not perish but have everlasting life." (v. 16)
- God's love is redemptive: "For God did not send His Son into the world to condemn the world, but that the world through Him might be saved." (v. 17)
- God's love is transformative: "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." (v. 18)
