Passage
Blessed are they that mourn: for they shall be comforted.
Blessed are they that mourn: for they shall be comforted.
Matthew 5:3 Blessed are the poor in spirit: for theirs is the kingdom of heaven.
Matthew 5:4 Blessed are the meek: for they shall possess the land.
Matthew 5:5 Blessed are they that mourn: for they shall be comforted.
Matthew 5:6 Blessed are they that hunger and thirst after justice: for they shall have their fill.
Matthew 5:7 Blessed are the merciful: for they shall obtain mercy.
The verse centers on "blessed", "mourn", "shall", and "comforted". It is saying that the verse draws attention to "blessed" and "mourn", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "Blessed are the meek for they shall..." into verse 6's "Blessed are they that hunger and thirst...", so "blessed" and "mourn" 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 "mourn" with trust shaped by these words, not by a vague optimism outside the passage.
