For I am about to do something new. See, I have already begun! Do you see it? I will make a pathway through the wilderness. I will create rivers in the dry wasteland. Isaiah 43:19 ESV
God is saying that he is about to do something new. This means that it has not been done before. God is a God of the impossible. He is able to make a road (pathway) in the wilderness. He can create a river in a desert. These are unusual miracles. What miracle are you believing God to do in your life? He can do it!
