Imagine you're making a list of things you'd like to accomplish in your life. You'd probably prioritize things according to how important, or how difficult, they might be. Learning how to play the piano wouldn't require as much effort as raising children. When we petition the Lord for His help, we tend to think He views our needs the same way, as if healing a serious illness would be more difficult for Him than relieving our discomfort from the flu. Nothing is too hard for the Lord, and we'll see how that fact plays out today for Judah. As the people are surrounded by enemies and strife, they will take comfort and have faith in the fact that their God is infinitely powerful.
