How to get a christian to stop trying to convert me?

just reciprocate...preach your religion and insult his...mirroring people does wonders..pisses off the cocky ones like nothing else

Welcome to the club brother .

Such types of people think that it's a kind of duty to convert everybody so NO you can't stop him by words and I guess next time he tries to convert you you'll have to use your fists .

Let the punching do the talking

The only way your religion will ever survive is if it has substance. If it's a fad, you'll ultimately lose whether you're pestered by a Christian or not.

Insulting the Holy Ghost is an unforgivable sin. Do it in front of him and he'll have no point to try and convert you anymore.

Threaten they're going to hell. That normally makes them go into a schizo-stress-mode for a few days till they see their pastor on Sunday.

If it's on the internet, stop the chat or stop sending messages to him.

If it's in real life, walk away.

I tell them they are scaring more people away from their religion than they will ever attract, and that you will happily swim in the lake of fire rather than listen to their crap.

Then stop asking the Christian around for a Bible study.

Tell him that if he is anything to go by, you really don't want to convert to Christianity. (And I don't think I blame you anyway. Sorry about that.)

Tell them you have AIDs of the soul and if you come in religious contact with them they will get infected and their faith will vanish. This will make them run.
