When we feel that we have a need, such as a need to control a situation or a need for a certain outcome, or a need like a health need or a sickness or financial need, if it seems like that need won't be met we will enter into fear.
Now notice that we don't necessarily become afraid because of the thing that we are in need of, but because the need isn't being met.
When we have a need, we think it is real, and important. We think it is the truth. So if that then isn't being met somehow, we are now actually afraid that we are going to be helpless, and that makes us even more afraid.
So then, we will think that we're experiencing fear and that we're afraid because such-and-such a future is going to happen, or such-and-such an outcome is not going to be the one we want to happen. And then we'll fixate on the 'being afraid of that future' as though this is the primary problem.
But it's not really the fear that's the problem.
It's the fact that you perceive you are 'in need' that's the problem. This perception of yourself as needy, i.e. lacking, i.e. defective or broken or diminished or limited etc... is the root cause behind the entire fear drama.
And what's that all to do with?
Well, you can only believe that you have a lack or a need when you believe you are *separate from God*. God supplies all needs, so without God you MUST see yourself as impoverished, under-served, lacking and empty. And so you SEE a need - an absence of what should be present (God) - within you.
You think that meeting this need somehow without God will solve the problem, but you can't actually meet this need without God. Or you can at least pretend you can, by taking and getting from others. In effect, by theft. But this won't make you feel good. And then what happens when this need can't be met, because you can't find someone to either give to you or for you to take from? Then you are stuck and terrified.
The real situation here, then, isn't the fear about the need not being met, and it's not about having the need and feeling needy, it's about you not being with God. That's the real problem. You need to get back in touch with God and reconnect with God SO THAT you trust and depend on God, SO THAT you receive from God abundantly, and SO THAT God is permitted by you to help you. And then, it's not that God will help you 'with' that need so much, as that the restoration of your intimacy with God UNDOES the entire foundation of being 'in need' in the first place - because all neediness is really the need for God.
Once you get God back, the need drops away, and all of the seeming 'symptoms' of lack and emptiness and limitation and sickness fall away, and therefore so does the fear.
Love is always the answer to every problem. Love is all you need.
