Matthew 5:6

Blessed (joyful, nourished by God’s goodness) are those who hunger and thirst for righteousness (those who actively seek right standing with God), for they will be (completely) satisfied.  

When we were born again and excepted Jesus as our Lord and Savior, we gained right standing with God. We can be completely satisfied in righteousness through Jesus.  Jesus cleared away our sins, and when God looks at us, He sees Jesus.   Which means all guilt and shame have washed away at the cross.
