Question: How can I reply someone who persistently invites me to his activities of another faith to try to convert me, despite knowing I am not interested?
Answer: If invited again, how about thanking him, and replying by inviting him to your faith’s activities too, suggesting that if attends a proper basic course with you, you might attend his activities? He is unlikely to join in…
Respectfully explain then, that just as he is uninterested in other faiths’ activities, you share similar sentiments. You can also add that if he attends your activities, he might realise why yours are already adequate for you.
