Let us now consider the sparkling things lying on the carpet. Is the light contained in them? No. There is no light in them, but they reflect the light from the gaslight. The wood of the mantelpiece reflects the light. Its purity makes it able to reflect. If there were some other dark substances here, they could not reflect the radiance. If I take this brass cup and hold it against the light, its shadow will be very thick and dark. If I hold my handkerchief against the light, its shadow is not so dense. The substance of the handkerchief allows the light to pass through it. If I were to hold a glass against the light, its shadow would be very light. This shows us that the more the particles of any object group and collect together, the less it allows the light to pass through it. From this we see that it is not God's fault if one is wise, another foolish, one is virtuous, another a sinner. The light of God is always shining there, but according as we allow it to pass, we reflect its brightness less or more.
