King Benjamin said the following:

But ye will teach them to walk in the ways of truth and soberness; ye will teach them to love one another, and to serve one another. And also, ye yourselves will succor those that stand in need of your succor; ye will administer of your substance unto him that standeth in need. (Mosiah 4:16–17)

In 1832 the Lord said the following through the prophet Joseph Smith:

Wherefore, be faithful; stand in the office which I have appointed unto you; succor the weak, lift up the hands which hang down, and strengthen the feeble knees. (D&C 81:5)

When we give, we are fulfilling the commandment to help others. I am reminded of what the Quaker Minister Stephen Grellet (1773-1855) wrote:

I expect to pass through this world but once. Any good thing, therefore, that I can do or any kindness I can show to any fellow human being let me do it now. Let me not defer nor neglect it, for I shall not pass this way again.
