All that I can tell you is this:
Jesus commanded his disciples to go and make other DISCIPLES. When I used to preach on the streets, I lived in New Jersey, and I preached pretty frequently in New York. Mostly in the Bronx, but also in Manhattan and Brooklyn at times (I also preached in New Jersey). One of the people that I preached on the streets with lived in Pennsylvania, and I used to teach Bible studies at his apartment. When people got saved on the streets of New York, I would drive from my home in New Jersey every Saturday, pick those people up in New York, and then take them all to Pennsylvania where I spent hours seeking to disciple them. If they fell away sometime after that, then that is on them. At my end, I did what Jesus instructed us to do.
