It does not have to be in a church building. It can be on our bedroom floor, in the car, or on a tree stump in the middle of the wilderness. God's arm is not shortened that it cannot save. No one is out of the reach of God, anywhere, anytime. And she is not out of the reach of prayer.
Prayer can reach into the deepest depths of anywhere.
I received the Holy Ghost without knowing that there was any such thing. I believe that God had to do it that way with me in order to extricate me from the deep pit of sin I was in. I had to have the power to lead me out of the awful wilderness of delusion and sin. The kids and I bought a Bible, and they would read while I drove. We began to have an appetite for the Word of God.
