Christ baptized no one with H2O -- John 4:2
But His disciples did, as the same verse tells you. Not sure what your point was, but Christ would baptize with the Holy Ghost, not with water. And that could not happen until He had ascended on high and poured out the Holy Spirit on the day of Pentecost.
It is significant that when Peter preached the Gospel on that day, he made it clear that anyone who repented and believed must be baptized immediately. Thus those 3,000 people who were saved were also baptized by immersion the same day.
And that was the apostolic pattern throughout the book of Acts. Again when Peter preached the Gospel in the household of Cornelius, those who received the baptism WITH the Holy Ghost (indeed all who believed) were baptized immediately. In fact Peter COMMANDED that they be baptized, and he was simply following the commandment of the Lord (Matthew 28:19; Mark 16:15,16).
The commandment for believers to be baptized has never been rescinded, but Peterlag (who started this thread) is now trying to promote that false teaching. There are also many Hyper- or Ultra-Dispensationalists who claim that Christian baptism is no longer necessary, since Spirit baptism is all that is required. But that is FALSE DOCTRINE.
Water baptism is not an option, but a commandment. It does not wash away sins, but it produces a good conscience toward God. That the believer has immediately obeyed Christ, and this is his or her first act of obedience. There is of course, much more to believer's baptism as taught by Paul.
