Susan's spirit is with you always. Her soul is with God, her Heavenly Father forever, because Jesus is a conqueror of death. It means death has been abolished. It means that your grave and mine, and the graves of our dear dead, shall be empty sometime. The light of the Risen Lord is our guide through the gloom.
Death is conquered.
But Jesus was willing to die for us on the Cross. After 3 days, He conquered death and rose again. The grief that we feel over the death of a loved one is not deeper than the agony of the Man Jesus of sorrows has become. However, the Risen Lord is the Hope for mankind, paving up a journey to eternal life - a journey to Hope. By faith, we enter into a journey to Hope with peace.
