Blessed are those who hunger and thirst for righteousness, for they will be filled. -- Matthew 5:6
What does it mean to hunger and thirst for righteousness?
The Bible often uses food and eating to describe aspects and phases of studying, meditating upon, and filling one's self with Scripture. God's Word is described as "food." Food can be milk, which is only suitablefor babies or thosewho are new to spiritual truths. Food is also described as bread, or meat. God's life within the believer is described as living water, new wine, honey. Food can be tasted, wasted, vomitted up, spat out. If there is a "natural" way of eating, there is also a way of looking at the natural symbol in a spiritual way.
Those who hunger and thirst for righteousness are people who desperately long for rightness in their spirit, soul, and body. They long to speak rightly, to think rightly, to love rightly, to feel rightly, to do right actions, to have the right kind of life working in their spirit, soul, and body.
This desire is not a whim. It is a deep craving for God which no earthly thing, no human mind-games can quench. This is not the playful whimsy of a dilettante. And it is certainly not something the slothful person could have becvause the spiritually lazy person isoften easily-satisfied with the wrong kind of spiritual food.
Only those who thirst for God with all their hearts are promised fulfilment
