D&C 18

After mention the joy the Savior experiences as well as that joy we shall experience as souls repent, the Savior teaches -

"...you have my gospel before you, and my rock, and my salvation.
18 Ask the Father in my name, in faith believing that you shall receive, and you shall have the Holy Ghost, which manifesteth all things which are expedient unto the children of men.
19 And if you have not faith, hope, and charity, you can do nothing."  (Doctrine and Covenants | Section 18:17 - 19)

We presently in stake PEC have been discussing how to implement one of the goals of the Brethren to increase missionary work and reactivation.  My point is verse 19...unless we have faith, hope, and charity which in my mind means that we "serve" or become servants to our fellowmen, it is a waste of time.
