God did *not* "will" it, mama. If you want to say He "allowed" it (and "it" is something different for each of us), understand that He allowed it in the sense that He "allows" His world to function according to its natural tendencies and natural laws. He does not meddle, generally speaking, with the workings of the world. When He does, it is called a miracle, but it wouldn't be right, or just, or even good, if He were constantly sticking His fingers in to redirect the order of things. And they would cease to be miracles. It is sin, and sin only, which causes death and hurt and grief. I learned a long time ago that He does not ask anything of us that He has not already done, and done to an infinite degree.
So grieve, but do not rage; weep, but know--
know in your head and heart and bowels--that He weeps with you, and, like you, longs for the day when all things will be made new. And trust Him, that in His providence and might, He will, indeed turn the greatest grief to something beautiful.
