God hasn't left us! He isn't the one creating the drugs, starvation and famous people. Remember in the beginning when God gave Adam and Eve a choice to disobey him and eat the fruit or obey and not eat of it. This is free will. God gave us choices, He doesn't control how everyone acts.
He gave us a goal, to go to Heaven, and we must use our free will in a good way to get there. If we pray to Him, He will guide us and help us along the way. But some people make choices that affect others. God didn't make them do it. Welcome to the World
