Neal A. Maxwell
"Another vital source of renewal is expending some of our energy by striving with the less active. Serving in this way keeps the giver from becoming weary or from fainting in his mind, making possible 'striving with unwearied diligence that they may bring the remainder of their brethren to the knowledge of the truth; therefore there are many who do add to their numbers daily' (Helaman 15:6). Assisting in such reclamation actually gives us added energy. We are energized and empowered, like the father of the prodigal, who ran to greet him 'when he was yet a great way off' (Luke 15:20). Such real love keeps us from becoming too tired to reach out." (If Thou Endure It Well, p. 116-7)
