No biblical authority, no theological authority, just my own faith here.
Mortality is the nature of man. Nothing about man is inherently immortality. Immortality is only the nature of God. So, the spirit of man must be taken by God, and made immortal. Love is how He does it, and love must be reciprocal. He loves you. You need to love Him.
The absence of love is death. Normal, inevitable, and ordinary.
