you've missed the point
Nef is a christian becuase she follows Christ and has her house solidly built on a rock. She is not the fool. The foolish man that rejects Christ has built his spiritual life on sand. Again, you focus on the external and miss the entire point.
I wouldn't have said anything and just lol'd until you posted that.
Good thing your religion hasn't brain washed you to be judgmental of others beliefs though!
