JESUS told His disciples to go preach the Gospel, baptizing them in the Name (singular) of the Father, and of the Son and of the Holy Ghost.
What is the name of the Father?
Joh_17:6 I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word.
JESUS is the Father's name.
Joh_14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
The Holy Ghost's name is JESUS
Act_20:28 Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
That's Holy Ghost's own blood.
With this revelation Peter stood up on the day of Pentecost with the other 11, baptized in the name of JESUS Christ. He did not say: I baptize you in the name of the Father and of the Son and of the Holy Ghost. He said with the revelation of the Name of the Father and of the Son and of the Holy Ghost, he invoked the name of JESUS Christ.
But for those who do not have a pure heart towards God seeking Him with a pure heart, they will never see it.
Isa 28:13 But the word of the LORD was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little; that they might go, and FALL BACKWARD, and be broken, and snared, and taken.
Some people believe we are given Word here a little and there a little so that they may make it. No to the un pure heart it is to make them fall backward and be taken because they serve God halfheartedly.
Who was it that Jesus baptized in water? How many did Paul baptize in water? Did Paul preach water baptism?
