I like the Lords question to Adam, "why dost thou offer sacrifice?" Adams reply " I know not save the Lord has commanded me." In third Nephi the Savior told the Nephites to meat together often. Sometime the simplest answer is the only answer this is what faith requires of us. There are many Sundays I do not want to go to church. For many different reasons. It does not make me anything but human. But I still go because The Lord commands me to. It is interesting to note I learn something about me and the gospel and my relationship with others each time I am obedient. I do not know what my being there does for others. My faithfulness just may be what helps somebody else to be more faithful. We in our ignorance depend on each other in many different ways, many we do not know about or understand.
