Unforgiveness is lonely and bitter place to live.
5:4 Blessed are those who mourn,
for they will be comforted.
People who mourn are capable of forming relationships. They love other people and can allow
themselves to grieve their loss when those people are gone, but someone who does not mourn
has no such relationships. They have set themselves apart from loving human interactions and
cannot mourn for they do not feel warmth. These must be lonely and miserable people.
