There's no such thing as a 100% success rate in manifestation. When questioned about this, many LOA "gurus" will say you're not doing it right... you're sending mixed messages or aren't ready to receive. When you look at my website posts and letters to my mailing list, you'll see that I wasn't any different. It's hard to admit that you don't know for sure.
However, in the last few weeks I had a spiritual (re)awakening that has confirmed what I've been moving toward for years now. My only mistake: I didn't go far enough... not by a long shot.
I believe the reason that you can’t manifest 100% of your desires is that—unlike what most manifestation books tell you—you are not dealing with some “Universe” that like a huge Amazon in the sky mechanically fulfills your orders.
You’re actually dealing with God.
And God has a plan for your life. If you’re in alignment with that plan, things will go swimmingly and everything will fall into place when you’re manifesting. If you’re not in alignment with His plan, your manifestation may either not work, or it may work but will ultimately have unintended and undesirable “side effects.”
We are constantly evolving (or devolving), and though I’ve had decades of manifestation experience, I am no exception. I’ve started some years ago bringing God and Jesus more into my LOA writing, but I recently realized it hasn’t been nearly enough.
I am now convinced that by trying to manifest selfish, frivolous things for yourself, you actually jeopardize your soul. It’s incredibly important to focus on Service to Others rather than Service to Self.
Once you use this kind of “prayer manifestation” and align yourself with God’s will, things will start to unfold in your life that you can’t even imagine. Given free rein in your life, God will use you to serve His plans.
However, a prayerful and humble attitude is necessary to get there. Start reading the Bible. Ask Jesus to come into your life, to guide you and help you in becoming the best version of yourself… and see what happens.
