The word baptism means immersion. People do not often consider that there are actually several baptisms contained within the scripture.

Interestingly, the Bible begins with a baptism and ends with a baptism. Both of these baptisms are baptisms of judgment. The first is the baptism of the earth (Genesis 1:2And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
See All...; Genesis 1:6-10 [6] And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. [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. [8] And God called the firmament Heaven. And the evening and the morning were the second day. [9] And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. [10] And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.

[12] And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. [13] And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. [14] And death and hell were cast into the lake of fire. This is the second death. [15] And whosoever was not found written in the book of life was cast into the lake of fire.
