In your opinion what causes christians to believe in Jesus

[John 6IX Breezy]

I mean, you're personifying the fig tree story to push it to absurdity. The story isn’t about trees trusting God—it’s about people bearing fruit when they appear outwardly religious. I don't see why that should be a contentious lesson. If anything it shows it's not enough the believe in Christianity, faith actually has to do something productive.
