Why do you think god created a world full of so much suffering?

To seriously answer your question, god created every thing BUT he is not the ruler of this world. Jesus said him self "far be it from the true God to act wickedly, and the almighty to act unjustly!"-job 34:10 here's another one "the whole world is lying in the power of the wicked one." -1john 5:19 and one more "when under trial, let no one say: 'i am being tried by god.' For with evil things god cannot be tried nor does he himself try anyone."-james 1:13
