The poor and the poor in spirit. The poor, poor means you have nothing or not a lot. Poor in spirit means when you are drained spiritually of God, for example you could be a billionaire and still be yearning for something (God), and you could be very sad (empty).
“Good desires”, good desires are when you have the need (desire) to do good/help the world be a better place. For example having the desire to do a bottle drive and donate to charity,work in a soup kitchen for the homeless, etc.
I think that our school and other schools should bring money to school once every moth and by the end of the year we could donate the money to the less fortunate or help build a shelter. Or every 2 weeks or something classes all around the globe could go outside and pick up trash, a simple thing that could help the world in the future.
