“Blessed are those who mourn,
for they will be comforted.”
Jesus taught that those who mourn are blessed. He means what we might call the righteous mourners. Mourning over sin, beginning with their own. Mourning over the brokenness and degradation of the world caused by evil. Mourning over the abject suffering that continues in the world unabated.
Jesus mourned. We see this when he wept over his friend Lazarus who had died, sorrowful over that, but also empathetic with others who were weeping. And he wept over Jerusalem, since they had failed to receive him as their true King. He wanted to bless them, but couldn’t.
There is no end to the sadness of this world. If we in Christ don’t enter that, then we’re not following or becoming like the one we profess.
