What criteria does god use when he decides to intervene?

- According to the UN World Food Programme, 3.1 children die each year due to hunger and malnutrition.
– In 2011, an earthquake off the coast of Japan caused a tsunami that killed 15,884 people.
– In 2004, an earthquake in the Indian Ocean resulted in a tsunami that killed between 184,167 and 230,273 people in 15 countries.
– In 2010 an earthquake hit Haiti, resulting in the death of at least 92,000 people.

But god is credited with saving a bus driver’s life, or helping the Miami Heat win a basketball game. If god intervenes, how does he choose when to intervene. Should we be grateful that god intervened to help the Red Sox win or saved someone’s life in the context of the sampling of death and suffering that is provided above?
