remember that the word 'baptize' simply means 'immerse'; not 'immerse in water'. for example, consider this scripture:
(Mat 3:11 KJV) 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:
(Mat 3:12 KJV) Whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire.
it seems clear that John the Baptist is saying that he immerses people in water, but that Jesus would immerse people in the Holy Spirit.
now look at this scripture:
(Rom 6:1 KJV) What shall we say then? Shall we continue in sin, that grace may abound?
(Rom 6:2 KJV) God forbid. How shall we, that are dead to sin, live any longer therein?
(Rom 6:3 KJV) Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
(Rom 6:4 KJV) Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
(Rom 6:5 KJV) For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
(Rom 6:6 KJV) Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
obviously, assuming that the word 'baptized' means 'immersion in water' would not make sense in this context.
notice what the author of Acts quotes Jesus Himself as saying:
(Act 1:1 KJV) The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach,
(Act 1:2 KJV) Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen:
(Act 1:3 KJV) To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:
(Act 1:4 KJV) And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me.
(Act 1:5 KJV) For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.
here again John is referred to immersing people in water, and Jesus is referring to immersing people in the Holy Ghost (Holy Spirit).
now look at this scripture:
(Mar 16:15 KJV) And he said unto them, Go ye into all the world, and preach the gospel to every creature.
(Mar 16:16 KJV) He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
(Mar 16:17 KJV) And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
(Mar 16:18 KJV) They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
obviously many people believe that Jesus was talking about immersing people in water, but it is also possible that Jesus wqas talking about immersing people in the Holy Spirit, especially since He is quoted making the difference between what He baptized (immersed) in (the Holy Spirit)versus what John the Baptist baptized (immersed) in (water).
look at one more scripture:
(Joh 3:5 KJV) Jesus answered, Verily, verily, I say unto thee, Except a man be born of water andofthe Spirit, he cannot enter into the kingdom of God.
(Joh 3:6 KJV)That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
many believe that Jesus is referring to water baptism in John 3:5, but others would argue that John 3:6 interprets Him to be referring to physical birth as the unborn child is immersed in water in the mother's womb.
one last thing to look at:
(Joh 4:1 KJV) When therefore the Lord knew how the Pharisees had heard that Jesus made and baptized more disciples than John,
(Joh 4:2 KJV) (Though Jesus himself baptized not, but his disciples,)
(Joh 4:3 KJV) He left Judaea, and departed again into Galilee.
it is worthy to note that there is no direct statement in scripture that indicates that Jesus (our example) ever immersed anyone in water.
you need to do your own research and seek God's leading for yourself in this, as there are many opinions that can be argued based on what scriptures are selected as being relevant, and there is not agreement in the Body of Christ today as to what exactly is the Truth about baptism.
