The body hath need of every member

Therefore, take with you those who are ordained unto the lesser priesthood, and send them before you to make appointments, and to prepare the way, and to fill appointments that you yourselves are not able to fill.

Behold, this is the way that mine apostles, in ancient days, built up my church unto me.

Therefore, let every man stand in his own office, and labor in his own calling; and let not the head say unto the feet it hath no need of the feet; for without the feet how shall the body be able to stand?

Also the body hath need of every member, that all may be edified together, that the system may be kept perfect.

Doctrine & Covenants 84:107-110

There is work enough for everyone and every person should be included in the work, entrusted with whichever tasks they are capable of undertaking.
