The Mishna in Perkei Avos tells us that the world stands on 3 things(Torah/Avoda/Chesed). Rabbeinu Yonah's understanding of these words is that Hashem's purpose for creating the world was for these 3 things to occur (For people to learn torah and daven and to help each other).
This mishna really seems to highlight the significance of all 3 of these actions.There are so many parts to Hashems amazing universe and everything was created in order to bring about these things.
It is our great privilege and honor to be able to be involved with these amazing mitzvos. We can really be motivated to daven learn and do chesed if we appreciate the significance of these actions.
