He is merciful and forgiving, gentle and kind. And because He cannot work against Himself, He cannot do evil. In fact He is aware of our suffering, and He grieves when we are not happy. And He wept for Jerusalem because of the twisted passions that had taken away its peace. How often would I have gathered your children together, even as a hen gathers her chickens under her wings and you would not.
Mercy is love grieving.
The grief and suffering of Jesus was the ultimate expression of the Divine love for humankind. He came into the world to fight beside us and within us against the subtle hellish urges that threatened the existence of any genuinely human love. His soul was grieved for the misery of Israel. He took our infirmities and bore our sicknesses. In all their affliction He was afflicted.
