Read: Matthew 5:1-12
"Blessed are those who hunger and thirst for righteousness, for they shall be satisfied. (Matthew 5:6 ESV)
The Sermon on the Mount, recorded in Matthew 5-7, is one of the most widely taught passages of scripture. The first portion is frequently referred to as the Beatitudes. Jesus' purpose in sharing this message was to influence people to forgo their desires for things beyond the Kingdom of God.
You will be blessed by yearning for, and indeed, living off of Christ's righteousness. We possess no righteousness except for Christ's. His goodness, his holiness, his perfection is the root of righteous satisfaction.
We can, and should do good works in this life. However, they will never make us righteous. They will never make us holy. They will never satisfy. Only Jesus can and will. Let us all seek after and for righteousness.
