Waiting with Confidence

I (Bethany) am reading the book of Isaiah. As I was looking at the study notes, here is the cross-reference verse that I came across (or rather God had planned for me to read). Romans 8:25 But if we look forward to something we don't yet have, we must wait patiently and confidently. Okay,I admit I am not the most patient person, so that was a good reminder. However, what stuck out to me more was the word confidently. Waiting confidently. Interesting. it is one thing to sit around and wait...with some semblence of patience...but waiting confidently--what does that mean? I think it means that while waiting I need to keep doing what needs to get done, being confident that things will come together & trusting God.
