Nothing escapes God's knowledge. This is proved by the witness of the Scriptures and the analogy of the sun, which, although created, yet by its light or heat enters into all things.

"God is not accustomed to refusing a good gift to those who ask for one. Since he is good, and especially to those who are faithful to him, let us hold fast to him with all our soul, our heart, our strength, and so enjoy his light and see his glory and possess the grace of supernatural joy."

Saint Ambrose
