The Bible Says , "Repent and be baptized, every one of you, in the name of Jesus Christ for the remission of sins. . ." (Acts 2:38). There is therefore no question as to whether or not you should be baptized. The questions are how, when, and by whom?
It would also seem clear from scripture that those who were baptized, were fully immersed in water. Here's one reason why:
"And John was also baptizing in Aenon near to Salim, because there was much water there..." (John 3:23).
If John was merely sprinkling believers, he would have only needed a cup full of water.
The Philippian jailer and his family were baptized at midnight, as soon as they believed. So what are you waiting for?
Who should baptize you? It is clear from Scripture that other believers had the privilege, but check with your pastor, he may want the honor himself.
