Possibly a contentious unbeliever will maintain that we worshiping images in our churches are convicted of praying to lifeless idols. Far be it from us to do this. Faith makes Christians, and God, who cannot deceive, works miracles. We do not rest contented with mere colouring. With the material picture before our eyes we see the invisible God through the visible representation, and glorify Him as if present, not as a God without reality, but as a God who is the essence of being.
In fact, the whole earth is a living icon of the face of God.
