John 12:24-25: Very truly I tell you, unless a kernel of wheat falls to the ground and dies, it remains only a single seed. But if it dies, it produces many seeds.Anyone who loves their life will lose it, while anyone who hates their life in this world will keep it for eternal life.
Here is a beautiful experience, recounted by a woman who died (in clinical terms) at the hospital. Jesus Christ came to her, as a being of pure golden light, who glowed through the heart with a blue star.
The woman (Charmian Redwood) knew that she had touched the eternal. Upon returning to her body, and recovering from her illness, Charmian reoriented her life according to sacred values. This short video is quite affecting.
