"Love...cannot be expected to last forever unless it is continually fed with portions of love, the manifestations of esteem and admiration, the expressions of gratitude, and the consideration of unselfishness." -President Spencer W. Kimball
When my husband and i were engaged we came across this quote in an Ensign. We were so in love and so desired for those feelings of love to last forever.  When we read this we really took to heart his counsel and hoped that we would continue to act on it when we were married. It is definitely a good reminder and inspired counsel from a prophet of God.
