Are you telling me that you're the reason people consider Jesus's Baptism a side-show?
Are you telling me that if I share the Gospel with a person on the side of Mount Everest, and that person receives Christ . . . they can't go to Heaven because we couldn't melt diddly piddly water for a swift and stupid dunking? No way.
Are you telling me that I share the Gospel with a person in the middle of the desert, where there is no water, that they can't go to Heaven because we couldn't find any piddly diddly water for a swift and stupid dunking? No way.
Our God is reasonable and rational. As said, God does not depend upon any worldly object so as to create expiation for Sin and the lifting of the Evil Sinful Nature.
Colossians 2:10 plainly teaches what it is that makes us "whole" and complete in Christ . . . and it has nothing to do with physical water. Jesus defeats Satan through His Spiritual Circumcision . . . not a bin of physical water.
