That's another wondrous blessing of the gospel - we mourn those who die but we do not mourn without hope. In the acute and even chronic pain of separation, as overwhelming the grief may be, with the blessings of the gospel, there is always a beacon of hope in the darkness. This beacon may appear dim and distant but it is there to comfort us in our darkest hours. We can see this beacon as we let our faith break through the wall of despair. Eventually this beacon will grow brighter until we are able to embrace once again the source of the light as we cross from this life to the next and are reunited with our loved ones.
Sometimes the light of these loved ones blesses in this life in our times of sorrow. In the October 2000 General Conference, Elder Robert D. Hales spoke on suffering but more specifically on experiences that help us overcome suffering. He missed the April 1999 and October 2000 General Conferences due to multiple surgeries. I remember parts of his talk vividly - some of what he said resonated strongly with me while I watched and listened to him, an apostle of the Lord. As he was suffering, in pain in the hospital, Elder Hales reflected on the blessings of the gospel.
"On a few occasions, I told the Lord that I had surely learned the lessons to be taught and that it wouldn't be necessary for me to endure any more suffering. Such entreaties seemed to be of no avail, for it was made clear to me that this purifying process of testing was to be endured in the Lord's time and in the Lord's own way. It is one thing to teach, 'Thy will be done' (Matt. 26:42). It is another to live it. I also learned that I would not be left alone to meet these trials and tribulations but that guardian angels would attend me. There were some that were near angels in the form of doctors, nurses, and most of all my sweet companion, Mary. And on occasion, when the Lord so desired, I was to be comforted with visitations of heavenly hosts that brought comfort and eternal reassurances in my time of need."(Hales, Nov. 2000 Ensign, Online Source).Sometimes angels visibly comfort us in our dark hours. As members of the Church we are entitled to the ministering of angels as we live worthily. These angels are not always seen but sometimes they are; when they minister unto us they provide great comfort and hope.
