And I know someone's going to say, "Well, God chose you." But, God loves everyone that way. How is it different for any one person. Besides, when you have high-functioning autism, it's hard enough trying to have relationships with people you can sense with your five senses. So imagine how much harder it is to try and have a relationship with someone you can't sense at all.
God loves people as individuals and builds unique relationships with them, including interaction, time spent together, creating memories and even doing things for them they don't see until later. It may not be easy to sense God with physical senses, but unlike people, God is 100% honest, 100% understanding, and consistent; God will not throw you away or decide not to care about you. As long as you remain open and willing in your heart, God will make a way for relationship. And as your bond with God grows you can interact in deep and meaningful ways that you can sense, even if it's not exactly the same as physical senses (although sometimes even that is possible, and some day it will be normal when we are with God).
I don't know all the obstacles high-functioning autism presents to creating a bond with someone, but I believe God is greater than such a diagnosis, and it is important as new creations that we don't build our identities on the brokenness that occurs in this world, by focusing too much on such terminology. It is not who we really are, even if it is part of our experience for a time. There were times when I couldn't really feel normal human feelings and God brought it back over time, through personal growth, risks, through desire which catalyzes faith and prayer, through revelation about things in the past and spiritual things in the present that were blocking me from feeling things that were normal for everyone else, but which I had forgotten.
God knows how to put you back together, if that is the issue. and Sexuality with all its difficulties, is as I see it, an expression of how deeply we are meant to connect to others and the profound power of relationships to create and enrich life.
