6.Blessed are the clean of heart for they will see God.
This beatitude calls us to desire to be holy people-- people who are charitable,who are chaste,and who embrace God's truth.In particular it calls us to avoid sexual sin.
8.Blessed are they who are persecuted for the sake of righteousness for theirs is the kingdom of heaven.
The final beatitude reminds us that following Christ's call will sometimes cause people who have not yet embraced the Gospel to react angrily and even violently.We endure their ridicule and even persecution with the patience and forgiveness of Christ.
