When we are in pain and anguish it is helpful to remember our resurrection is coming and then to be gentle with ourselves.
When grieving it is especially important to not expect ourselves to feel any differently and to know that it will indeed pass.
Grieving however does not pass all of a sudden. Grieving comes and goes, it is a healing process.
Just as Jesus after the crucifixion, it took him a few days to rise again, but he did indeed rise.
Pain and suffering are temporary and if we do not resist them, they will surely pass gently over time.
