Courage to face death and the unseen worlds requires a strong foundation in faith that is not based upon unknowingness, but rather, from boundless faith based upon knowing the truth through experience.
Once you know the truth, it is impossible to no longer see it, it becomes self-evident. When you comprehend that the entire created world we have here in the material realm is actually the combined gifts and donations of spiritual beings who are expecting us to resurrect and disenchant matter from its frozen spell and take it back into the spiritual world through our own higher perceptions, through our own moral thoughts, feelings, and deeds.
