Putting a new church together is hard work! Joseph Smith didn’t do it alone, but with help and delegation to responsible and honest men.
One such man was William W. Phelps who was in the printing business. Joseph Smith was inspired to give him a responsibility that is recorded in Doctrine and Covenants section 55, verse 4.
“And again, you shall be ordained to assist my servant Oliver Cowdery to do the work of printing, and of selecting and writing books for schools in this church, that little children also may receive instruction before me as is pleasing unto me.”
These two men were given an important charge–compiling curriculum about spiritual things so that children could understand them. That must have been a daunting task but I bet with a lot of evaluating information and prayer, Oliver and William were able to produce materials to help teach the children.
