St John Chrysostom says that it is a great blessing from God that some parts of the Scriptures are clear while others are not. By means of the first we acquire faith and ardor and do not fall into disbelief and laziness because of our utter inability to grasp what is said. By means of the second we are roused to inquiry and effort, thus both strengthening our understanding and learning humility from the fact that everything is not intelligible to us.
Hence, if we take stock of the gifts conferred on us, we will reap humility and longing for God from both what we understand and what we do not.
~St Peter of Damaskos
