Loneliness is linked to death nearly as much as sorrow. When a loved one passes out of this life it leaves an empty place. This is especially true in the loss of a spouse, child, or parent but also with close friendships and other close family ties.
The space in our lives once filled by someone dear is not filled up by time or activity or someone else. It can't be filled with something or someone else but we can express this need to the Lord and ask Him to fill us with His goodness and presence.
