I believe much the same as you.
Spirituality recognizes that there is a world that is invisible to us and there are powers that we cannot see at work. There are also different types of spirtuality. The type that wishes to decieve and do harm, and the type that wishes to do only good and does so without any deciept whatsoever.
The type of spiritual person I long to be is the type that manifests the Holy Spirit in the sense of Gal. 5:16 and Gal. 5:25. (The fruit of the Spirit, in my own way.)
It isn't a steadfast condition. It is something that must be maintained. If you flounder in your spiritual life, you will lose something of it. You can get it back, but as with anything, it takes time and obedience. You have to be willing to pursue it. It's very easy to get side-tracked. That is something I struggle with.
I take my lead from reading about Jesus. I see in the Bible that He was a Spiritual person. He was NOT religious at all. (See how He reacted to the Pharisees!)
MY favorite shirt has emblazoned on the front: "Having a religion is against my relationship."
Following my spiritual instincts, rather than religious rules has truly made me a different and better person.
