Acts 2:36-41

36 Therefore let all the house of Israel know assuredly, that God hath made the same Jesus, whom ye have crucified, both Lord and Christ.
37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
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.
39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
40 And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation.
41 Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.

John 3:23-36

23 And John also was baptizing in Aenon near to Salim, because there was much water there: and they came, and were baptized.
24 For John was not yet cast into prison.
25 Then there arose a question between some of John's disciples and the Jews about purifying.
26 And they came unto John, and said unto him, Rabbi, he that was with thee beyond Jordan, to whom thou barest witness, behold, the same baptizeth, and all men come to him.
27 John answered and said, A man can receive nothing, except it be given him from heaven.
28 Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him.
29 He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled.
30 He must increase, but I must decrease.
31 He that cometh from above is above all: he that is of the earth is earthly, and speaketh of the earth: he that cometh from heaven is above all.
32 And what he hath seen and heard, that he testifieth; and no man receiveth his testimony.
33 He that hath received his testimony hath set to his seal that God is true.
34 For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him.
35 The Father loveth the Son, and hath given all things into his hand.
36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.

Matthew 3:1-17

11 I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire:

John was baptizing with water but Christ who is mightier (power and authority) will baptize you with the Holy Spirit (the word) and with fire (death)

John 4:1-3

1 When therefore the Lord knew how the Pharisees had heard that Jesus made and baptized more disciples than John,
2 (Though Jesus himself baptized not, but his disciples,)
3 He left Judaea, and departed again into Galilee.

John 7:37-39

37 In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink.
38 He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.
39 (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)

Isaiah 44:1-3

1 Yet now hear, O Jacob my servant; and Israel, whom I have chosen:
2 Thus saith the LORD that made thee, and formed thee from the womb, which will help thee; Fear not, O Jacob, my servant; and thou, Jesurun, whom I have chosen.
3 For I will pour water upon him that is thirsty, and floods upon the dry ground: I will pour my spirit upon thy seed, and my blessing upon thine offspring:

Matthew 28:18-20

18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
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:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

Acts 1:5

5For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.

1 Peter 3:21

The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:

Baptism saves us not by physically removing dirt, but by being a symbol of a believer's commitment to God for a clear conscience, achieved through Jesus Christ's resurrection.
