blind

The kids love watching their "Jesus video" that their cousins introduced them to.  They quote from it often...

Me: Callan, don't poke your sister in her eye.  She doesn't like that, and you could really hurt her eye.  Do you know what could happen if you really hurt her eye badly?

C:  No.

Me: She might have trouble seeing or even go blind!  That would be horrible wouldn't it?

C:  You mean like how Jesus made Saul's eyes go blind?
