St. Jerome immersed himself into the Word of God, studying it intensely for most of his adult life. This gave him a keen understanding, not only of the Bible, but of God and his plan of salvation.
We can all learn from St. Jerome's love of the Bible, though we don't always read it as often as we should.
Here is the collect prayer for St. Jerome's feast day, asking God to help us be sustained by the Bible as St. Jerome was fueled by it.
