Always be willing, even anxious, to help others. Nothing else you do will give you the same genuine satisfaction and joy within because, and I quote, 'when ye are in the service of your fellow beings ye are only in the service of your God' (Mosiah 2:17). Ignoring the needs of others is a serious sin.
As we give of our time, talents and resources to tend the needs of the sick, offer food to the hungry and teach the dependent to stand on their own, we enrich ourselves spiritually beyond our ability to comprehend.
