Jesus described our desire for righteousness as a hungering and thirsting. We should want to be righteous (“right with God”) to the point of doing whatever it takes (Scripturally) to gain that relationship. Are there things in life we need to get rid of – bad relationships, too much entertainment, bad habits, improper attitudes – that are keeping us from being close to God? Or are there things we need to add to our lives – studying the Bible more, repairing broken relationships, a commitment to meeting with our brothers and sisters in Christ as often as possible? When we do these things, we show our hunger and thirst for righteousness.
After you have had a large, cold glass of water (or milk) or a favorite meal, you feel good inside. Not only that, but your life is renewed and sustained. The same should be true when we “are filled” after hungering and thirsting for righteousness, which Jesus promises. We should have an inner peace knowing we have a relationship with our Creator and a reward in heaven. And our spiritual “life” is renewed and sustained for an eternity
