Prescribed Procrastination

Settle it therefore in your minds not to meditate beforehand how to answer -Luke 21:14

At first this sounds like the easiest commandment ever: Don't prepare. And it would be easy if it weren't for our instance on worrying. I know I'm going to arrested and suffer greatly for my faith if I don't give a good answer...but I can't think ahead about that answer. Yeah, that's pretty tough. Of course, I could think for months of elequent things to say and only end up fumbling over my words and robbing God of the glory of speaking through me.
