Reality is any activity we engage in that, either in the short term or long term, brings undeniable consequences in ourselves or those around us.
Though sometimes only to a small degree, our words and thoughts also constitute reality. Even though they do not immediately alter any physical material, at least not outside the neural pathways of those who give and receive them, still they are forged onto the canvas of the universe. Sticks and stones may break my bones and so can words and thoughts.
Let the church, then, create reality not only through her projects and programmes, but also through her prayers and prophesyings.
