Very good question. Pain forces growth and change. Pain is the stimulus for you to seek good. Pain intensifies your comfort, peace, happiness, your serenity when they come. Pain allows you to see what works in the world and what does not work in the world. Pain shows you where evil things lie. Pain evaporates all of the meaningless parts of the world and opens your eyes to what is truly important. Pain is the result of your own choices and those of your ancestors, the sins of your fathers have been visited upon you as well. 

Pain is not the path I wished for you but it is the path you have chosen and because I want you to love completely without My coercion and of your own free will I allow you to suffer the consequences of your own decisions because when you choose to love Me I will know that your heart is pure and that I did not coerce you and we will both know that this is the Truth.

But what do I know? I’m just a dummygod.
