We live in a world of human need. There are physical needs, emotional needs, and spiritual needs. We also live in a world of sin.
People hurt each other, neglect responsibilities, fight, argue, and do as they please.
We cannot change the whole system. In this world there will be offenses, sins, abuse, oppression, atrocities. Things will happen to people that never should happen. And because of that, there will be poor people, suffering people, miserable people, wretched people, as long as we are in this world. Mercy is more than a feeling of sympathy.
