God picks the God-seeker or God-lover, but in line with experiences or Consciousness (inner growth) if you like. I grew up in Christianity and one can perhaps say that my parents are responsible for this. Most of us are affected by our culture and countries when quite young.
As one grows older, one may stay the same or commit to something different or new. Still, a new birth is required for spiritual life proper and that may come by reading scriptures, or attending discourses, listening to a video or friend and so forth. Spiritual awakening is a new or sudden way of looking at the Light... an illumination or uncovering of the Heart ... a revelation of something which has never left us but was simply hidden until revealed. God, Grace and maturity reveal this Light.
There is then a transformation, acceptance and totality of the oneness of God without boxes.
Loosely speaking, there are two ways of looking at the spiritual Path. One is a mental way and the other is the way of the Heart. Both are part of the plan, but the second is faster, safer, surer..
