We do see, however, a conscious decision for profession of Christ involved in certain baptismal events:
That was long winded, I know my bible. Yes that is for adult new Christians we also see entire house hold get baptized
Anyway this is just your opinion with nothing to back it up
I have 2000 years of church teaching and tradition
Acts 19
King James Version (KJV)
1 And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,
2 He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost.
3 And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.
4 Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
5 When they heard this, they were baptized in the name of the Lord Jesus.
6 And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.
Baptism following belief in Christ is the logical conclusion we reach from what Scripture teaches. I would point out that here we see both water Baptism and the Baptism with the Holy Ghost.
We see Cornelius baptized after hearing the Gospel:
Acts 10:34-40
King James Version (KJV)
34 Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons:
35 But in every nation he that feareth him, and worketh righteousness, is accepted with him.
36 The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all)
37 That word, I say, ye know, which was published throughout all Judaea, and began from Galilee, after the baptism which John preached;
38 How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him.
39 And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree:
40 Him God raised up the third day, and shewed him openly;
Then he is baptized, both with the Holy Ghost, as well as in water:
44 While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.
45 And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
46 For they heard them speak with tongues, and magnify God. Then answered Peter,
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.
It is Peter, after seeing that they had been Baptized with the Holy Ghost, who calls for them to be baptized in the name of the Lord.
That this is the time they are saved in seen in Peter's commentary:
Acts 11:12-18
King James Version (KJV)
12 And the Spirit bade me go with them, nothing doubting. Moreover these six brethren accompanied me, and we entered into the man's house:
13 And he shewed us how he had seen an angel in his house, which stood and said unto him, Send men to Joppa, and call for Simon, whose surname is Peter;
14 Who shall tell thee words, whereby thou and all thy house shall be saved.
15 And as I began to speak, the Holy Ghost fell on them, as on us at the beginning.
16 Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost.
17 Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God?
18 When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life.
Water Baptism follows the Baptism with the Holy Ghost, which is more simply stated as "immersion into God," for it is the time at which men are reconciled to God, and brought into Eternal Union with Him.
One can baptize a baby, but, men do not transfer the Holy Ghost in salvific effect. Salvation is the result of trusting Christ by coming into obedience to the Gospel. When a baby is baptized, they do not become regenerated, they simply get wet. The same is true of those who are baptized but have not yet been saved.
God bless.
