A God who knows everything cannot have emotions. The Bible says that God experiences all of the emotions of humans, including anger, sadness, and happiness. We humans experience emotions as a result of new knowledge. A man who had formerly been ignorant of his wife's infidelity will experience the emotions of anger and sadness only after he has learned what had previously been hidden. In contrast, the omniscient God is ignorant of nothing. Nothing is hidden from him, nothing new may be revealed to him, so there is no gained knowledge to which he may emotively react.
We humans experience anger and frustration when something is wrong which we cannot fix. The perfect, omnipotent God, however, can fix anything. Humans experience longing for things we lack. The perfect God lacks nothing. An omniscient, omnipotent, and perfect God who experiences emotion is impossible.
