How can God be real if there is so much suffering?

Sometimes I struggle with the fact that there is SO much suffering in our world, how could God be real…...but have you ever noticed how indifferent and apathetic people can be towards say the homeless, or struggling?

Are those people sort of prophets in a sense? The children who die every minute? To break our hearts and make us realize how selfish we are? How apathetic?

If this is true, no wonder we cannot believe in God, because selfishness is the opposite of love.
