Rip-off artists often see Christians as easy marks... That needs to change. Yes, Christians need to ‘forgive’ but not before serious repentance on the part of the ‘sinner’. God is forgiving - he can see into the human heart - we can’t. And to act like we can is to assume we’re on God’s level. The term blasphemy comes to mind.
You’re correct about that I believe. One of the best Christian con men was/is the so called “Painter of Light” who continues to hood wink the network of Christian groups where he has actually made people think his reproductions are investments.
I also have witnessed how the con men in the Mormon communities are able to get very close to unsuspecting believers. Also there are lots of get rich quick pyramid schemes presented.
