Notice another note that John strikes in verse 10: “In this is love, not that we have loved God but that he loved us and sent his Son.” What is he guarding against in that denial: “In this is love, not that we have loved God...”? He is emphasizing that the nature and the origin of love does not lie in our response to God. That is not where love starts. That is not mainly what love is. Love starts with God. And if anything we feel or do can be called love, it will be because we are connected with God by the new birth. - John Piper, Finally Alive, p. 155.
