when God uses glee and st. john of the cross in the same sentence

Bear with me, there is a method to the madness.

We must then dig deeply in Christ. He is like a rich mine with many pockets containing treasures: however deep we dig we will never find their end or their limit. In every pocket new seams of fresh riches are discovered on all sides...The soul that longs for divine wisdom chooses first, and in truth, to enter the thicket of the cross. (st john of the cross)
