If all one sees is water in the so called, great commission...then one is missing out....And that is the passage I'm speaking of...
I hope we agree.
Previous to the 400 years of silence, the law and prophets were taught.
(From Moses to John the Baptist)
Beginning with John the Baptist the the Kingdom began to be taught
(the one who comes after me will baptise you in the Holy Spirit and fire).
Jesus moved from the external law of Moses to internal abstract inner thoughts. Matthew chapters 5,6,7
So
The majority of people would see water. The Nile, Red Sea, washings, crossing Jordan.
But
The inner thoughts about:
Poor in spirit
Hunger and thirst for righteousness
etc.
these are new concepts to most.
If the concept of baptism is brought up, water is the major thought at the time of Jesus.
However
Immersion into abstract thoughts is more of a Greek concept (IMHO)
Not that Jesus taught Greek mythology, but Jesus taught Gods thoughts. Jesus taught the multitudes in parables ( external ) but taught the disciples about (inner) love, joy, etc.
Really the Baptism at Pentecost is the real inner ( heart, mind immersion - law placed in heart and mind).
Language classes are sometimes taught as immersion classes. No word for word translations, but another language foreign to what has existed. (This is a hard concept for a redneck to explain).
Example
A gentile had to be immersed in the concepts of God. Leaving their Godless former beliefs behind, and becoming immersed in The one true God . No paganism spoken, or hidden in this class.
