God promised He would always provide for us. The struggle comes when He provides in ways we don't expect. Sometimes it's in ways we REALLY don't expect. It's in those moments we have to look at our situation and like Mordecai, say, "Perhaps..."
Mordecai's faith never wavered. He didn't know how the situation was going to play out, but he knew that God would provide deliverance for the Jews. He was convinced the provision would come through his niece, Esther, who had been put in a remarkable position having come from extremely unremarkable circumstances.
How have you discounted the ordinary circumstances in your life? Perhaps they're the very ways God wants to provide for you.
