Acts 19:4
Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
Then said Paul,.... In reply to their answer, understanding them that they were baptized by John, he takes it up, and gives an account of John's baptism: showing how agreeable it was, and that it was the same baptism with the baptism of Christ, being administered in his name:
John verily baptized with the baptism of repentance; which required repentance antecedent to it, and was a fruit and effect, and so an evidence of it:
saying unto the people; the people of the Jews, the common people, the multitude that attended on his ministry:
that they should believe on him, which should come after him, that is, on Jesus Christ; so that he preached faith in Christ, as well as repentance towards God; and made the one as well as the other a necessary prerequisite unto baptism; which shows, that his baptism and Christian baptism are the same.
