All who are truly repentant and are wanting to follow the Lord will be baptized when they are made aware of that need. In my case the repentance and the water tank were almost 10 years apart. That should never be. No one told me it was required and my own bible study did not bring me around to that for years. It took me hanging out with christians from another faith tradition (Church of Christ) before I saw that I was not in compliance with scriptural commands.
I believe I was saved for those 10 years, but others disagreed. So eventually I studied it out myself. It was then that I saw the command to be baptized was NOT addressed to the new believer but rather the evangelist. And if you bring up Peter's statement in
Acts 2.38, think about it. Peter was fulfilling his own obligation in preaching the gospel, not passing the baton or declaring that the requirement was on the new believers.
