Passage
Blessed are they that mourn: for they shall be comforted.
Blessed are they that mourn: for they shall be comforted.
Matthew 5:2 And he opened his mouth, and taught them, saying,
Matthew 5:3 Blessed are the poor in spirit: for theirs is the kingdom of heaven.
Matthew 5:4 Blessed are they that mourn: for they shall be comforted.
Matthew 5:5 Blessed are the meek: for they shall inherit the earth.
Matthew 5:6 Blessed are they which do hunger and thirst after righteousness: for they shall be filled.
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 3's "Blessed are the poor in spirit for..." into verse 5's "Blessed are the meek for they shall...", 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.
