This is how we know what love is - by way of his substitutionary and propitiatory death. And as we become increasingly Jesus-centred we'll become increasingly other-centred. Not just in sentimental words of love, but in love that acts to meet needs.
This sets an agenda totally opposed to the spirit of our age, indeed of every age since the days of Cain - an age in which we're so curved in on ourselves that we don't know what love is. The gospel takes us away from ourselves, to Jesus to believe in him and onward to others to serve them.
