The documents focus on God providing for His people through grace alone as seen in the water from the rock in Exodus, Paul's warning against relying on works for salvation and instead receiving it as a free gift, and the parable of the laborers in the vineyard where all receive the same wage regardless of how long they worked. The Transfiguration prefigures our adoption as sons through Christ and the glory we will share with Him, revealing Jesus as the fulfillment of the Law and Prophets and confirming His divine nature.
