...consider Mosiah 4:26. And now, for the sake of these things which I have spoken unto you--that is, for the sake of retaining a remission of your sins from day to day, that ye may walk guiltless before God--I would that ye should impart of your substance to the poor, every man according to that which he hath, such as feeding the hungry, clothing the naked, visiting the sick and administering to their relief, both spiritually and temporally, according to their wants

  There are several reasons why we might home teach:

• Desire for praise or other earthly reward.
• Good companionship
• Fear of God's punishment or Church censure.
• A sense of duty. We've been taught to fulfill our callings and keep our covenants.
• Desire for heavenly reward.
• Love of those to whom we are assigned.

  (The reasons listed above were adapted from Elder Dallin H. Oaks book, "The Pure in Heart", pages 39-49. It is one of my favorite General Authority books.)

  None of these motives is bad but surely love or charity is the purest motivation. How do we develop love if we don't feel it now? We serve and grow to love those we serve. So if you are a Priesthood Home Teacher or a Relief Society Visiting Teacher and don't feel motivated to fulfill that calling, just do it. You will become motivated by the purest of motives as you do.
