Each beatitude, which simply means supreme blessedness, begins with the phrase “blessed are.” These words imply that whoever participates in that right heart attitude will benefit from being in a perpetual state of receiving God's favor. It was this continual blessing that Jesus knew was going to fulfill the needs of His followers. The fourth beatitude is for those who hunger and thirst for righteousness. Jesus said, “Blessed are those who hunger and thirst for righteousness, for they shall be filled.” (5:6)
Jesus performed a miracle that day when He took two loaves of bread and five fish, and divided them among a group of over five thousand. The book of Matthew states that they all ate and were filled, and there were twelve baskets filled with what was left. God desires to give above and beyond the need for those who come to Him with an appetite.
Each individual who earnestly and actively seeks after the things of God will be filled according to their appetite. And appetites change as the individual matures spiritually. Whether it is a brand new Christian who wants to learn about what it means to be saved, or a seasoned believer who wants to understand the Father heart of God, all can be satisfied according to the need. The key is to seek.
To hunger and thirst for righteousness indicates a constant desire to search out something that the believer knows is good for them. A newborn baby intrinsically knows that food will satisfy their hunger. They do not think twice about the validity of their physical need, nor do they neglect their need to eat. They simply cry out for what they know is good. The same is true for a believer. There should be no question of the necessity of spiritual food. Nor should one neglect their need for fulfillment. Instead, God desires for them to cry to Him and allow Him to generously provide for their need, just as He promised.
