Let's keep learning about the Sermon on the Mount.
We've learned about the first of the Beautitudes:
Blessed are the poor in spirit, for theirs is the kingdom of heaven.
The second one is:
Blessed are those who mourn, for they will be comforted.
Mourning means you are sad about losing something, usually because someone died.
Jesus is saying that if you are sad, he will always be there to comfort you.
