If you weren’t afraid, it wouldn’t be your destiny. What God has for you is bigger. It’s something that you haven’t seen: new levels of influence, favor, opportunity. There is potential in you waiting to be released.
God knows what you’re going to need, when you’re going to need it, and how to get it to you. That problem you’re worried about? God has the answer already in route. The vindication, the healing, the breakthrough is already set up.
If somebody left you, you have to realize their part in your story is over. If they walked away, then you don’t need them. If God allowed it, then that means they’re not a part of your destiny.
