For all you anons who are playing with gnosticism / luciferianism / esotericism / any knowledge-based ism that you think will lead to some higher/better state, here is a warning. It is a true account.
Someone whom I know very well has had two NDE's and this is what she experienced.
When she was six years old she nearly drowned; she reached that place where she stopped struggling and experienced what she describes as the most blissful feeling of calm and all surrounding love and well-being. Then she was rescued from the water and given the kiss of life and brought back from near death. Her memory was of a blissful experience that she almost longed to return to. Remember - she was only six years old.
At the age of seventeen, she had a romantic disappointment involving the man she loved and her best friend that left her feeling her life wasn't worth living and it would be better for all if she were end it. She took a massive overdose of co-codamol. As she fell unconsciouos she had the most terrifying experience; hellish, demonic hands reached out to claim her as one of their own. They were exultant and all-consuming in their eagerness to take her. Instinctively she knew they had a right to her soul and she could not resist their claims. But she came from a Christian family and, terrified, she called out: "Jesus, please save me. I'm so sorry. I didn't know. Please, Lord, save me." As she cried out, a brilliant figure she knew was Jesus replaced the grasping, demonic hands, and the next she knew she was being violently sick. She lived to tell me the tale and it has changed her life. She knows that the first NDE when she was a child, was a foretaste of heaven, it was so blissful. Then she learnt that as an adult, heaven wasn't her automatic destination after death - she had made wrong choices. Mercifully, God gave her a second chance and as she repented, in her dying moments, Jesus gave her back her life and she has followed Him ever since.
Heaven is real. Hell is real. Jesus is real. He alone is the WAY, the TRUTH and the LIFE and NO man comes to the Father, our Creator, except through Jesus. No amount of gnostic or esoteric knowledge will save you from God's justice - deserved punishment. But faith in the substitutionary atonement of Jesus for your wrongs will save you from God's justice.
