JESUS' BAPTISM ENDED WATER BAPTISM:
1. End of John the Baptist's administration and baptism with water.
2. Beginning of Jesus' administration and baptism with FIRE:
" I indeed have baptized you with water: but ..."
" But" used here as a contrasting conjunction means what's on the left side of "but" will be different from that on the right side.
e.g. John eats apples "but" Jesus eats oranges ...would state that Jesus does not eat apples e.t.c..
So water baptism must decrease as Fire baptism (Gospel teaching of knowledge) increase.
Fire and Holy Ghost means KNOWLEDGE and UNDERSTANDING.
Fire - knowledge of the gospel teaching of Jesus only.
Holy Ghost - understanding of the gospel teaching of Jesus only.
knowledge + understanding = wisdom.
wisdom is power.
However the Holy Ghost does have unlimited other functions.
Matthew 28:19 has ABSOLUTELY NOTHING TO DO WITH WATER;
Matthew 28:19 Go ye therefore, and TEACH all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost(UNDERSTANDING):
The word "baptizing" is a participle, not a verb. Baptize in Jesus' teaching(KNOWLEDGE), NOT water.
