Stevers has started a thread about faith you might like to follow. In it he quotes from the Effortless Success course -
"To trust in the force that moves the Universe is FAITH. Faith isn't blind; Faith is Visionary. Faith is believing that the Universe is on our side and the Universe knows what it's doing."
It is indeed a great leap to go from believing their is no guiding force to trusting in God. I would suggest that a first step is simply to open your heart and mind to the possibility that there might actually be a proactive energy into which you could tap. With your question here, I think you have already taken that step. The next one is to start noticing what evidence there is that your life is being (or has been) affected positively by outside events. (Many use the word 'blessed' for this concept.)
You know, you actually report trusting in the 'security' of your 9-5 job providing for your future - yet told us not long ago that the one you had was ending. By nature the employee's position is temporary and can be terminated at any time. It is only a vehicle to provide for your family's immediate needs. If you already have another job to use for that purpose, you have been affected positively by an outside event. (There are many people looking for jobs who don't find them these days.) Surely you have been 'blessed' to have the means with which to purchase the Effortless Success course. Use it, doing the things it teaches, and notice the positive things that just 'show up' in your life. Don't feel that you must interpret this in any way - just notice what is happening.
If you remember, the Law of Attraction tells you that the amount of emotional energy you attach to an outcome is what attracts it to you. Accordingly, noticing the things you enjoy in abundance attracts more experiences with enjoying and abundance. But the other side of the coin is that noticing fearfully the things you lack attracts more experiences of fearing and lack. So the trick is to notice when you find yourself worrying about the future, tell yourself to stop that, and direct your thoughts to the things that you have enjoyed in the past, are enjoying in the present, and/or could be enjoying in the future. As long as you are actively putting energy into your life (not just hanging around waiting for it to happen) the energy you attract will show up in your life.
May you create some abundance in your life today.
