Romans 5:8.
The supreme demonstration of God's love.
Any response is our affair.
Accepting this requires taking on the full mystification of the Atonement doctrine, which is made even more confusing within the context of Trinitarian theology.
Romans 5:9 gives the full context, though, and it doesn't make for pleasant reading:
Since, therefore, we are now justified by his blood, much more shall we be saved by him from the wrath of God.
It seems that even this 'love' comes with a threat: "Do this, or else..."
Which is also couched in nonsensical theology: God sends his Son, who in some sense is also God, to take the burden of our 'sin', which 'sacrifice' we must accept, or the same 'God' will give us what-for. Why not just forgive people straight off, if they sincerely repent? God's peculiar antics of breaking up the Trinity, ('kenosis') and coming down to earth seem a very strange performance to be getting involved in. Perhaps all this meant something to St Paul, when he thought it up, but it amazes me that anyone should find some deep truth in it, except of a metaphorical kind.
However, all such matters have been done to death here before, and no doubt no one is interested in receiving attempted explanations. The complexities of the Atonement doctrine seem as various as the number of people who try to explain it.
"God is not a God of confusion". hmmm...
