If God existed. (Dharma)

Q: If God existed... 
why is there war, people who is starving, 
people who is ill... 
It is not only non-believers that get sick! 
Everybody do! 
I feel panicked about this world 
and want to change the whole world, 
make everything good but I know I can't.

A: If there is a government, then why are people suffering in jail? Because they have disobeyed the law. The government certainly has the power to release them, but has them in jail for their rectification and the protection of society.

The Lord has His own kingdom, the spiritual world, where there is no suffering of any kind. Each of us voluntarily, individually, left that world and came here. In this material world, we act according to our own desire, rather than the desire of God, and therefore we are individually responsible for the results of our actions. If our actions are against God's laws (dharma), then we suffer. We get our reactions not only in this life, but over many, many lifetimes, so that my suffering now may be due to sinful actions I performed many lifetimes ago.

There is no unfairness. Everyone enjoys and suffers exactly what they deserve and all suffering is meant for the eventual enlightenment of the person - to bring him or her back to the original spiritual position of loving God.

Change of the world starts with changing ourselves. It depends only on our decision. The other solutions (political, economical etc.) were shown to be inefficient
