There is no such thing as coincidence. Everything in your life is there to assist you in some way. Whenever you keep encountering similar situations over and over again, they are there to remind you of what you have chosen to learn.
Even the song on the radio, or the billboard on your way to work, can be tools to help you stay focused on your path of learning. If you find yourself dismissing a piece of information, because “it is just a coincidence” then you are not listening to what Spirit is trying to tell you. When something shows up in your life, even when it is unplanned or goes against what you thought you wanted, it is still there for you to learn from.
