why wouldn’t The Lord Jesus Christ just say “baptism” instead of "Ye must be born again of water "?
Jesus does say “baptism” in Mark 16:16
“He who believes and is baptized will be saved; but he who does not believe will be condemned”
But in The Gospel of John, we are given the “theological” meaning behind that comment.
Keeping in mind the chapter and verses were not added to the bible for some 1,200 to 1,500 years, and that chapter divisions can lead to a break in the chain of thought that the original author did not intend, let’s go back to John chapter 1.
John is going to explain whey we need to both believe and be baptized, and not just believe alone to be saved.
John 1:11-13
He came to what was his own, but his own people did not accept him. But to those who did accept him he gave power to become children of God, to those who believe in his name, who were born not by natural generation nor by human choice nor by a man’s decision but of God.
Here John writes that Jesus gave “power” to those who believed in him to become children of God.
John 2:23-25
While he was in Jerusalem for the feast of Passover, many began to believe in his name when they saw the signs he was doing. But Jesus would not trust himself to them because he knew them all, and did not need anyone to testify about human nature. He himself understood it well
Here John writes that people began to believe in him because of the signs, but Jesus did not trust himself to them because they only believed with human knowledge.
Jesus is going to explain how we receive the supernatural belief that is required and John will next introduce Nicodemus an an example of how this is.
John 3:1-2
Now there was a Pharisee named Nicodemus, a ruler of the Jews. He came to Jesus at night and said to him, “Rabbi, we know that you are a teacher who has come from God, for no one can do these signs that you are doing unless God is with him.”
John 3:3
Jesus answered him, “Truly, truly, I say to you, unless one is born anew, he cannot see the kingdom of God.”
John 3:5
Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.”
Here John explains that we have to be baptized so we can receive that supernatural power from the Holy Spirit that is required to become Children of God, and that Jesus will trust himself to us.
We know that it is water baptism that Jesus is speaking of because in Chapter 1 he speaks of both spirit and water.
John 1:32-33
John testified further, saying, "I saw the Spirit come down like a dove from the sky and remain upon him. I did not know him, but the one who sent me to baptize with water told me, 'On whomever you see the Spirit come down and remain, he is the one who will baptize with the Holy Spirit
And right after his conversation with Nicodemus, Jesus is Baptizing with his disciples, the only place that it is mentioned that Jesus was himself present with his disciples when they were baptizing.
John 3:22-23
After this, Jesus and his disciples went into the region of Judea, where he spent some time with them baptizing. John was also baptizing in Aenon near Salim, because there was an abundance of water there, and people came to be baptized,
For a great explanation of this I would recommend the number 11 program of “
Our Fathers Plan” by Scott Hahn. He covers it in the first part of the audio program.
Also in MP3 format “Gospels 2”
(I might be wrong on the program number but I think it is 11, or the one before or after it.) sorry.
