As water cleanses the outer person from soil and sweat, so the blood of Jesus Christ cleanses the inner person from the stain of sin. The most critical mistake one can make with regard to baptism is to believe that it is necessary for salvation. And you will receive the gift of the Holy Spirit. However, the book of Acts itself shows that baptism is the sign of conversion, not the means of conversion. Although baptism is not the means by which we are saved, it is the means by which we are set apart.
Some groups prescribe a particular pattern for the baptism rite itself.
One group teaches that unless you are baptized using the correct formula, which they prescribe, you are not truly saved. In their theology, those who are baptized in the name of the Father, Son and Holy Spirit are not truly born again. In sharp distinction, Scripture does not point people to a prescription or to a magic mantra, but rather to the very person of Jesus Christ. When a physician provides someone who is sick with a prescription, their trust is not in the paper on which it is penned, but in the person who issued it. So it is with baptism.
