Hey Father Mike, I'm going to go get some lunch. I'll be back in 30.
If it's God's will, you'll be back in 30.
Do you not want me to go get lunch?
No, I'm just saying that you may be back in 30 minutes or you may not be, and that will be God's will.
Do you mean I can have longer than 30 minutes for my lunch break?
If it's God's will. Although, God's will may be for you to get hit by a bus as you cross the street coming back from the Subway. Get me a meatball sub, please.
