As Jesus moved forward in time he encountered spiritual oppression relating to spiritual and physical death(e.g. "When you're dead, the soul is weak and unconscious. When the body dies, you die. When you're dead, you can't move, so you remain frozen and rot. When you're dead, you can't feel, see or hear. When you're dead, you can't repair or resurrect the body." etc. etc.)
The above is "The Devil's Mental/Spiritual Straitjacket" that entrapped souls for eons. Christ's resurrection was and still is a victory over the darkside. "Oh, death where is thy victory? Oh, grave where is thy sting?"
