Think about something you really want to happen. Do you trust, are you 100% certain, that God will make it happen? If not, why not?
My terminology in saying that God will make it happen is not the best. A better way to say it is that God and you will make it happen as He expresses through you. How can you know with certainty that something is going to happen? Well, you have the POWER to make anything happen. But I am not talking about moving mountains here (although that is the case) --- I am referring to something like the publication of a book, a promotion at work, a solution to a problem. Your task is to believe with 100% certainty and trust that it will happen. How it happens, and the time frame it happens, is not up to you. That is where God comes in. You have expressed your need, and you know that it will be taken care of. All you have to do is sit back and follow the guidance of what you need to do to make it happen. You don't have to worry about the details, as you completely trust the end result.
Unfortunately, what happens for a lot of people is that they start out with a very high trust level, and then something happens which makes them doubt a little. Instead of concentrating on the end result, they are worrying about the details, and they begin to doubt the end result. Something may happen after that which is "good". It reinforces their trust. Then another "bad" thing. You do not want to be smacked around by the daily ups and downs. These are appearances. Everything could look very bleak, but a "miracle" could happen at anytime. Miracles come about through 100% faith and trust. So make your perspective a very high one, and leave the "driving" up to God.
