One of the difficult things about trusting Holy Spirit is the idea of 'showing up' empty handed and not knowing what the heck to do, and yet things still working out 'in the moment'.
Usually our minds are filled with all kinds of predictive, planning thoughts which try to know, beforehand, what needs to be known in order to do whatever it is that needs to be done, at the time. And we won't budge if we don't know what's going to happen first, because we're afraid.
When Holy Spirit asks me to write my book for example, I hesitate with thoughts like "I don't know what to write" or "what will I write about". And then Holy Spirit will keep on reminding/suggesting, "book, book, book". And I will keep on protesting mentally, "what shall I do". What He really wants me to do is to just stop the mental chatter and sit down and start writing AND THEN in the moment, in the flow, in the spontaneous present, HE IS THERE, and He helps me write.
So then it ends up being, I didn't need to know, by myself, what to do beforehand, because by `just doing it` was an invitation to Spirit to join with me in the PRESENT and support me and help me spontaneously and unrehearsed.
Going to do something when you have to put aside all notion of knowing what it is you will do, and all plans, and all sense of "I can only do this IF I know what will do"... its very exposing. It makes me feel empty-handed and blindfolded and clueless. It doesn't exactly support a concept of ego confidence. It's more like, I have to `just do it` anyway with a tremendous call to have COURAGE and FAITH and TRUST.
So when Holy Spirit is urging you to do something, I think we have to remember to trust that He WILL be there in the moment with us and He WILL be helping us and he WILL be working through us. It's like you have to take the leap first AND THEN the wings appear. You act 'as if' you will have all the support in the world and then it shows up.
This is difficult to learn, because I'm so used to ... hah... being in control. Lol, (thanks HS for that insert). So used to being in the drivers seat and relying on prior learning (the past) and thinking (lol) that I can only do anything if it's been premeditated and planned out. This is an ongoing lesson for me and probably for many people, because the ego is basically the thing that comes between surrender/letting go and being too afraid to make a move when you can't yet see the safety net - a safety net that you don't even really NEED when Holy Spirit goes with you. "If you knew Who walks beside you on the way that you have chosen, fear would be impossible" - ACIM
The ego doesn't understand how to put trust/faith/spirit first and to expect support from outside of itself. It doesn't know how to let itself be abundantly supported or to be included in a bigger plan not of its own making. Holy Spirit has a plan. But it calls for us to step OUT of our own plan and our own controls - letting go of controlling all outcomes - so that we can step into the spontaneous flow of Spirit directing us and moving through us and healing through us. Which reminds me of this wonderful ACIM quote:
"I am here only to be truly helpful.
I am here to represent Him Who sent me.
I do not have to worry about what to say or what to do,
because He Who sent me will direct me.
I am content to be wherever He wishes, knowing He goes there with me.
I will be healed as I let Him teach me to heal." - ACIM
To just show up, ready, willing, available, to be directed and used by Spirit, with no prior agenda, with perfect willingness and readiness, as an agent of God, without necessarily knowing or needing to know who/what/where/why/how ... that's what I/we need to get to. To go around doing God's will, working miracles, healing people, teaching and inspiring people, being moved by Spirit and supported in 'supernatural' ways. We need to learn to trust in Spirit's support and that, if we leap first, then we will find the power to fly.
