Romans 3:12. Thanks to Jesus Christ’s work on the cross, we have a choice between being the old man separated from God or to be a new man in harmony with God. The new man is in continual relationship with God. The new man has God in him. The old man is separated from God and cannot but go a separate path from God. The old man chooses sin and is in fellowship with the devil, the flesh, and the world.

Revelations 21:8. The third type of death is Eternal death. Eternal death is eternal separation from God. If we have not accepted Jesus Christ as our Lord and Savior, we will face death that is eternal on Judgment Day. Eternal death happens because man chooses sin (disobedience to God), and thus, we choose to be separated from God. Separation from God first starts off as spiritual death, but it will eventually turn to eternal death. This is the death we never want to face. We need to believe what the Bible says about eternal death.
