As I read 2 Nephi 28:24 this morning these are the thoughts that went through my mind:
Working for the cause of the Lord will always be uncomfortable, challenging, or tiring. It is enjoyable and worthwhile, but it is not easy. See Matt. 16:24-27; Mark 8:34-38; Luke 9:23-26. We can liken our work in the Kingdom as if we were taking up our cross. It requires work, it requires spiritual, mental, and physical strength. It requires a firm testimony in the Son of God who carried the cross of the world on His shoulders.
