Why do we sometimes experience pain?

We think that the qualities of anger, envy, jealousy, pride, etc. are God-given, but it is not true. God does not make any distinction between people by granting positive attributes to some and negative qualities to others. All these differences are human-made and God has nothing to do with them. When our wish is fulfilled, we praise God. On the other hand, if something goes wrong, we attribute our failure to God and blame Him. God is only a witness to everything that goes on in this world, good or bad. He neither gives nor receives anything. All our sorrows and difficulties are of our own making.
