Just an honest question Jason,
What are you hoping to accomplish here? Do you think that pressuring someone into saying something accomplishes anything? As Christians this is not how we are supposed to be behaving. Jesus didn't force you to say He is Lord, that was your choice, and it was mine as well, but it is a CHOICE.
Even if you can get someone to repeat something, that will not change their heart. People can say all kinds of things, that doesn't mean that they are sincere. Sincerity is what matters when you confess Jesus as Lord, you must mean what you say.
I ask you respectfully to please stop antagonizing people. That is not how we are to treat others. As Christians, we are to love others and we do not force our beliefs on anyone.
