All suffering is a consequence of sin and sin originated in this world from mans disobedience. If man had obeyed the simple commands of God from the beginning, there wouldn't be any of the suffering we see today. Satan, the father of sin, loves to torture what God loves and it's very clear in the Bible that God loves children. Mans disobedience in Eden opened the gateway for Satan to cause utter destruction. Could God step in and prevent it? Yes. But He doesn't. Why? Because man needs to see the consequence of sin and straying from Gods path to be willing to turn away from it. People need an understanding of how adverse sin is to never want to do it again. But that doesn't mean that God doesn't grieve. Remember these are His children we're talking about. His heart burns for them every second. Most people think that He just sits back nd watches the world as if it were TV screen. But in truth, He’s with all of us e every minute. He suffers with us. He sent His own Son, spotless and pure, to die a gruesome death so that we might be saved. But one day all suffering will come to an end forever. God has every single life in mind as if each one was his only priority. Justice will be done to every living soul in the end. We cannot understand every aspect of the divine plan of an omniscient, omnipotent God. But we just need to know that He has assured a fair ending to this great controversy. It's not for us to try and fathom everything. That's where faith comes into the picture.
