One cowardly liar didn't want to pray for his god to appear before the end of the call (I understand, then it would definitely be clear that he's not there)
But he did pray for his god to appear in the area from 2 weeks to a month)
So, I set a reminder for myself to check in a month, let's see if it turns out that he's a complete liar and his god doesn't respond to prayers at all)
Or in a month I'll write that I've accepted Christianity :D
