So, the context of John 3:16 falling right after the conversation with Nicodemus lets the reader know that what is told in 3:16 is not so much a threat to the readers in general, but rather, merely a statement to Nicodemus as an individual as to what can come of his eternal life when he becomes a believer. If one was to read 3:16 on its own merit without putting in in the context of a conversation with Nicodemus, one might mistakenly see Jesus as being threatening or arrogant where he is actually being helpful and serving as a worthy advisor to Nicodemus. 3:16, then, by virtue of what precedes it, lends itself to being a very personal and giving moment displayed by Jesus as he lends caring advice to a man who would be well served to be less self-oriented and instead give his life to Jesus, son of God.
