This instance while I was doing pull ups. After doing as many pull ups that I could (that number is isn't important), I lifted with all my might, and went no where. "Just One More," said one of the people with me. I exerted all of my strength, but still couldn't pull myself up. The person with me held up my legs and told me to do a couple more pull ups. I pulled as hard as I could, and because he was supporting some of the weight, I got a couple more in. After that, I was totally exhausted.
Sometimes in life we feel that we are pushed beyond what we can handle. Sometimes we are. But it's during those times when the Savior is holding us up. That's when we feel we can't do it ourselves, so the Savior comes to our assistance and gives us a boost. Zeniff, in the Book of Mormon, knew he needed to rely on the Lord for strength. In his time of need he said, "Yea, in the strength of the Lord we did go forth..." (Mosiah 9:17). When we can't do it on our own, we shouldn't give up. We just need to look for the Lord's hand in our life. Once we do, we'll be surprised how often he really is there.
