God’s love was revealed among us in this way: God sent his only Son into the world so that we might live through him. (1 John 4:9)
Ask a typical (Protestant?) Christian why God sent Jesus into the world and they may recite John 3:16, but if you ask them to put it into their words, and they’ll probably say “to save us,” that is, they’ll focus on the “should not perish” part of John 3:16. And so God did. But both in both the gospel and the letter the focus is on the life that God brings to us through Jesus.
(There’s much more to be said on this, but my internet connection is wonky, so I’ll leave off now).
