Loss and suffering is part of this fallen world. When Adam decided to go independent of God just by relying on his own ability to choose between good and evil, he disconnected himself from the source of life and fell into sin. The result is fear, suffering, loss and death. Jesus came to redeem us from this death. But at times we do go through loss and suffering in our journey because that translates into a greater glory. He does not leave us alone as we go through it but strengthens us and enables us with His Joy. He also helps us to find who our Father is. It develops our invisible arm of Faith, which would not have developed any other way. Everything works out for good.
Here is a story of one family who found joy and faith in midst of loss and sorrow.
