Disclaimer: This is a recount of what I did when I had my experience that called me back to Christianity. This method may or may not help you. If it does, great. If you feel you need to modify it, feel free to do so. If it doesn't, don't worry or think there's something wrong. Rituals WILL NOT cause an experience but they can aid in seeing what is already present.

So first I laid out nine objects in a circle that made me think of God. Under one of the objects representing Light, I placed something representing Darkness to get the point to me that Light is over Darkness. In this circle of objects I laid out 8 tarot card each representing something particular about myself, A card representing how I saw my "higher" self, my current self, my life path, that which influences my path, totality, emptiness, knowledge, and wisdom. I sat in front of the circle with a keep sake from my Mom. I prayed, "Dear heavenly Father, I want to become the person you want me to be. I know there are powers which rule and influence my life but with you they hold no power over me. I want to move from ignorance to knowing who you are. I also hope I am granted the knowledge and wisdom to recognize who you are. In the name of the Father, Son, and Holy Spirit, may your Holy Sophia show me what you wish to to show me."

...And then I was called.
