Please accept my deepest condolences. The following words have helped many to cope with the loss of someone special. 1 Corinthians 1: 3, 4 states "Praise be the God and Father or our Lord Jesus Christ, the Father of tender mercies and the God of all comfort, who comforts us in all our trials..."
Our Father, Jehovah God, will help your family and friends cope with such a difficult loss. In 1 Corinthians 15:26 he promises us that "the last enemy, death, will be brought to nothing." I hope the family and friends can find some comfort in this promise.
