Section 4

This section is the famous missionary scripture. It sets forth the characteristics we should have to be effective missionaries and explains the importance and urgency of missionary work.

I hadn't noticed before that the revelation was given to Joseph Smith's father. Obviously all the revelations in the Doctrine and Covenants are written for all of us even tho they were originally given to one or more persons specifically.

Here are my thoughts,

Reasons for missionary work	Work hard and you will stand blameless at the last day
he that thrusteth in his sickle with his might, the same layeth up in store that he perisheth not, but bringeth salvation to his soul;	Not only are we doing a great work that brings greater happiness than anything else, but we are gathering blessings for ourselves, WE WON'T PERISH, and we bring salvation to our OWN souls
It gives 15 characteristics we should have.	I think doing missionary work helps to give us those characteristics; we shouldn't wait till we have them to start serving!
