We do not all receive blessings in the same way. Some, on receiving the fire of the Lord, that is, His word, put it into practice and so become softer of heart, like wax, while others through laziness become harder than clay and altogether stone-like. And no one compels us to receive these blessings in different ways. It is as with the sun whose rays illumine all the world: the person who wants to see it can do so, while the person who does not want to see it is not forced to, so that he alone is to blame for his light-less condition. For God made both the sun and man’s eyes, but how man uses them depends on himself. Similarly, then, God irradiates knowledge to all and at the same time He gives us faith as an eye through which we can perceive it.
~St Peter of Damaskos
