That is very unlikely. They are probably "softening" you up so that you are convinced that the LDS church is the true church. The next time you see them you could simply tell then that you have nothing in common with them, and that they should simply move on.
The last pair of Mormons that came to my house were ordered to stop coming because they were starting to believe me.
i was asked not to return to their church because the others there were raising uncomfortable questions after I voiced objections in their BOM study
i'm on a blacklist now.
i know this is an older thread, but chances are all of us will have such encounters. they are a wealthy and powerful organization, second only to the RCC, and particularly target evangelicals because those without a solid foundation are easily swayed.
Don't give up hope, keep telling the truth.
they thought they were sent to you to convert you but my God sent them to you to hear the truth. it is better we walk in faith than cynicism.
just focus on Christ in all you say to them and ignore everything else. He is all that matters. do your homework. be ready.
love them. be true.
