What would you do if there were standing 4 muslim brothers in front of your house door and asking you to open the door and to go with them to the mosque? :p
This happened a couple of times with me and my father just told them that he doesn't have time for them.
Should you tell them "I'm a Christian, so you've got nothing to find here" (and risking that they will kill you XD) or preaching to them the Gospel or just sending them away so they won't bother you?
Just curious how you would handle.
