I wish also to put up my view on this based on the scripture.
To be saved means entering into the God kingdom, and you cant JOIN Gods kingdom but you are born into it as He told to Nicodemus.
John 3:3
Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
How are we born becouse the natural types the spiritual, First is Water, Second Blood third is Life. in a normal birth.
Same happened onthe cross when they pierced Jesus, there came out water, blood and then His spirit which was His life.
In this KINGDOM Jesus gave the disciples authority of how to be born into it, moreso He gave PETER the keys to that KINGDOM to have power to open to anyone and close as in
Mathew 16:18-19
18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
When it came time for PETER to OPEN that kingdom he said it in
Acts 2:38
38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
(take note its PETER who begun to speak of all the disciples coz he was entrusted with the key of the KINGDOM by our LORD.
When Paul and Silas were realesed from the Jail when they went to a gentile Home they told Him
Acts 16:31-33
31 And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
32 And they spake unto him the word of the Lord, and to all that were in his house.
33 And he took them the same hour of the night, and washed [their] stripes; and was baptized, he and all his, straightway.
Baptism was required in that.
When the same PAUL met the Disciples of John the Baptist he asked them whether they have recieved the Holy Ghost they said no, and he asked them of which BAPTISM were you baptised (a crucial requirement) and they were baptized again in the name of JESUS CHRIST
ACTS 19:5
When they heard [this], they were baptized in the name of the Lord Jesus.
When Philip met the eunuch, He had to be baptised
ACTS 8:36-38
36 as they went on [their] way, they came unto a certain water: and the eunuch said, See, [here is] water; what doth hinder me to be baptized?
37 And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.
38 And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him.
(Even after the eunuch believing Jesus with all his heart Philip baptised him)
At cornelious house to GENTILES, even after believing on Jesus and even the spirit falling on them PETER demanded they be baptised
ACTS 10:47-48
47 can
any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?
48 And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.
My last Point will be on JESUS Himself as He was sending His disciples away He commissioned them to BAPTISE ALL NATIONS (not Jews only)
MATTHEW 28:19
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:
Am not trying to out do any one but saying in all this scriptures, baptism was and is a requirement to be born in the kingdom of God, coz it thru BAPTISM(WATER), CLEANSING(THRO BLOOD) and you will recieve a gift of the HOLY SPIRIT(LIFE) The three steps of birth.
