'We, in many cases, may, by the rule of the gospel, be obliged to give to others when we can't without suffering ourselves...If our neighbor's difficulties and necessities are much greater than ours and we see that they are not like to be relieved, we should be willing to suffer with them and to take part of their burden upon ourselves. Or else how is that rule fulfilled of bearing one another's burdens? If we are never obliged to relieve others' burdens but only when we can do it without burdening ourselves, then how do we bear our neighbour's burdens, when we bear no burden at all?'
Jonathan Edwards in Timothy Keller, Generous Justice, p.70.
