Commentaries:
We may deduce from God's instruction to the Israelites that they "should have no pity on" the wicked nations around them and that we should not pity ourselves for incurring the penalties of sins we chose to commit. Everyone is personally responsible for his own actions. In pitying ourselves, we say, "Poor thing, suffering for your own sins! It's all right if you sinned. You shouldn't have to suffer for it." Self-pity actually involves lying to oneself. It is a result of sin, and it is incurable without repentance (Jeremiah 30:15). Repentance from sin is the difference between self-pity and sorrow. Self-pity involves no repentance, while godly sorrow produces repentance (II Corinthians 7:9-10).
