A woman desiring to pray grabbed an empty chair and knelt before it. In tears, she said, “My dear heavenly Father, please sit down here; you and I need to talk!” Then, looking directly at the vacant chair, she prayed. She demonstrated confidence in approaching the Lord; she imagined He was sitting on the chair and believed He was listening to her…
God is everywhere, is available every time, and listens always.
