Physical death is the separation of the soul and spirit from the body.
Spiritual death is separation from God, who is life.Hell is not spiritual death. In Revelation 20:14, both death and hell are cast into the lake of fire, showing they are not the same.
Separation from God is separation from all that God is.
If God is eternal peace, then hell is eternal torment.
If God is light, hell is outer darkness.
If God is grace and mercy, hell is judgment.
If God is Holy, righteous, and pure, then hell is defilement, filthiness, and impurity.
If God is love and joy and peace, then hell is weeping and wailing and gnashing of teeth.A common question: “How can a loving God send people to hell for all eternity?”
But this question completely misses the truth of eternity.
When a person chooses to reject the reconciliation God has provided in His Son, a person has chosen to separate from all that God is.
The only possible result of such a choice would have to be hell.
It is the rejection of God.
