Passage
Blessed are the pure in heart: for they shall see God.
Blessed are the pure in heart: for they shall see God.
Matthew 5:6 Blessed are they that hunger and thirst after righteousness: for they shall be filled.
Matthew 5:7 Blessed are the merciful: for they shall obtain mercy.
Matthew 5:8 Blessed are the pure in heart: for they shall see God.
Matthew 5:9 Blessed are the peacemakers: for they shall be called sons of God.
Matthew 5:10 Blessed are they that have been persecuted for righteousness` sake: for theirs is the kingdom of heaven.
The verse centers on "blessed", "pure", "heart", and "shall". It is saying that the verse draws attention to "blessed" and "pure", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "Blessed are the merciful for they shall..." into verse 9's "Blessed are the peacemakers for they shall...", so "blessed" and "pure" belong inside that flow. In Matthew context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "blessed" and "pure" with trust shaped by these words, not by a vague optimism outside the passage.
