"What Do You Think?"

It's an inviting question.  It's nice because, when asked, it implies that you value the opinion of the other. It's open-ended and encourages dialogue, a sharing of perspective.

Asking God things like  "Is this who I should marry?" or "What should my career be?" are fine, but limited. They are flat while God's point of view tends to add dimension. (Often, God may expand our one-dimensional questions by responding with a question.)

In short, seeking God's entire perspective is better than having a vending machine for answers. Thus, homework: ask God what he thinks about something apparently small, and listen for a response. If you get good try something more weighty.
