We suffer a great loss, a separation from someone important to us. Separation or loss means we no longer have a vital ,ongoing, living relationship with this person---only memories. We no longer can talk with this person, hug or kiss this person, hold hands or walk down the street with this person, or do any one of a thousand wonderful activties with this person.
There are other losses too. We may lose a house, by fire or wind or water. We may lose a car, by accident or theft. We may lose our job, lose our church or lose any number of things important to us.
In the darkness of grief we can turn to the Lord, who promises His comfort and strength.
