That God separated the waters above the firmament from that below is important to understand. It's the difference between eternal life and death. It's a choice you need to make every day. The bread from heaven is the word of God which became flesh but the dust which Satan was cursed to eat is the lust of the flesh. Depending on your choice you can spend your life eating the flesh from above and live forever. Or eat the lust of your own flesh and end up in hell with satan. From this audiobook "The will of the Holy Trinity for Mankind" by Paul C Jong you can listen and learn exactly what choices God has given you.
