Desire and thirst both seek satisfaction. The psalmist was once envious of the boasting and prosperity of the wicked, and didn’t understand why God allowed it. Yet, he brought his concern to the Lord and received fresh understanding. In the place of his envy for what others had, the Lord gave him a new thirst, a new desire for God Himself. He lifted his eyes to heaven and saw the rich portion that was his, namely, the Lord.
All things on earth will fade. Our bodies will fail. Why thirst for things that do not satisfy? Why be envious of things that will not last? Instead, let your desire be for the Lord. Put your trust in the Lord Jesus, who said from the cross, “I thirst” (John 19:28), so that we might find our deepest desire satisfied in Him.
