It's not easy to love. It means you have to be responsible, to care for the other person, to place yourself at their service, to feel their pain, accept their worries as your own, to be vulnerable. To love the poor and afflicted means that you share their affliction, you co-miserate, you suffer with them. This why a person will only learn to love unconditionally and wholeheartedly, unless they first permit God to love them wholeheartedly and unconditionally. Once they do this, it simply an overflowing of love, like a cup held under the flow of Niagara Falls.
