Matthew 5:6, “Blessed are those who hunger and thirst for righteousness, for they shall be satisfied.”
Jesus said in Matthew 6:33, “But seek first His kingdom and His righteousness, and all these things will be added to you.” Christ is the revelation of God’s righteousness and God’s kingdom. To seek God’s righteousness and to seek God’s kingdom is to seek Christ. When we hunger and thirst for Christ, we are satisfied in the Lord’s Supper when we taste the sweetness of the forgiveness of sins as His body is present in the bread and His blood in the wine. Martin Luther said concerning this, “We have the clear assurance that God does not cast aside sinners, that is, those who recognize their sin and desire to come to their senses, who thirst for righteousness” (Luther’s Works, American Edition, 2:41). Jesus said to the Samaritan woman at the well, “Everyone who drinks of this water will be thirsty again, but whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life” (John 4:13-14). Those who thirst for righteousness get baptised into Christ, who is righteousness, and who imparts His righteousness to us by faith. His righteousness now imparted, we never again have to thirst for it, for His righteousness now belongs to us by faith (Romans 1:17; 3:21-22).
