Fasten seat belts, for a little more flyby milk doctrine.
The water was baptized in Gen 1:2, (see my post (My Brethren Water)).There needed be a heaven for the now Spiritual water, because in Gen 1:4 He divided light from the darkness, meaning there was darkness in the earth, and we know light, and the now Spiritual water, can not exist in darkness.
(Gen 1:4) And God saw the light, that it was good: and God divided the light from the darkness.
(Gen 1:5) And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
Immediately after God divided the light, from the dark, and declared it, it was morning. God then made a heaven for the now Spiritual water, before the darkness would come again.
(Gen 1:6) And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
(Gen 1:7) And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.
Water is from the earth where there is natural darkness, but the Spiritual water now has a place to dwell, and a direct connection to heaven, therefore is saved, and is able to bear witness on earth, but not able to bear record, because water is from the earth. This is very similar with us (saved),we live in the earth, but are not of the earth, and also have a direct connection to heaven through the Holy Ghost, and are able to bear witness in earth!
(Gen 1:8) And God called the firmament Heaven. And the evening and the morning were the second day.
(1Co 10:4) And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.
We have a physical, and spiritual connection with water through the Holy Ghost, just like any other spiritually saved brother or sister who testifies to Jesus Christ.
