Once we have called, our next step is to watch. He has never broken a promise and He is promising to show us great and mighty things we do not know. God finds joy not only in our asking but also in our anticipation that follows. Lets not rob Him of them!
This verse has SO much meaning to me... First verse I ever memorized because I opened my bible right to it in my quiet time after asking God to help me deal with much uncertainty... God hears prayers and this is one way he answers them! You just have to get in his word!
There was a point when I realized that every rebellious path my "you can't tell me what to do" heart led me down had left me sad and broken. That moment is when I first understood this verse.
