"Unless thy law had been my delights,
I should then have perished in my affliction."-- Psalms 119:92
Not after our trials, but during the very worst of them, we can experience happiness, delights or pleasure (Heb. shashua), by focusing on the law -- the word -- of God.
I am reminded of the vision of the Prophet Lehi, in which he saw a rod of iron representing the word of God, leading to the Tree of Life, the love of God. While partaking of the fruit brought ultimate joy, we can believe that the journeyers also experienced delight along the way by "holding to the rod."
