“Blessed are they which do hunger and thirst after righteousness: for they shall be filled," Matthew 5:6.
What is righteousness?
"Righteousness is holiness, likeness to God, and “God is love,” 1 John 4:16. It is conformity to the law of God, for “all Thy commandments are righteousness” (Psalm 119:172), and “love is the fulfilling of the law” (Romans 13:10). Righteousness is love, and love is the light and the life of God. The righteousness of God is embodied in Christ. We receive righteousness by receiving Him.
