What keeps us moving?

I feel that life is hard. And I ask myself this question, "why am I still pushing on?" I thought out that inspirational moments will propel me forward but eventually lose its momentum. But I wanted to know what would keep me constantly moving forward. I came across this scripture as I was reading in the Bible. In 1st John 4:18 it says "perfect love casteth out all fear". Then it took me to another scripture in the Book of Mormon, where Moroni says that he is "filled with charity which is everlasting love" (Moroni 8:17). Charity keeps me moving. "Charity suffereth long, and is kind, and envieth not, and is not puffed up, seeketh not her own, and rejoiceth not in iniquity, but rejoiceth in truth, beareth all things, believeth all things, hopeth all things, endureth all things." (Moroni 7:45) It is because of love that I keep pushing forward. My love for my family helps me to be a good son. My love for my future family helps me to be righteous and to get an education. My love for my Heavenly Father helps me to be obedient to His commandments and to serve one another. I know that if we are filled with love for each other, then we will never fail. We will push through the hard times that want to beat us down. Love is power that can move mountains.
