Faith through works

I don't understand why we need to go to church so often. Why do we need to have so many meetings? To learn the gospel? Is the gospel that hard to understand that you have to go for three hours or more a week to understand the essential message?

What a complete waste of time.

What if a stake president took his thousands of members and had them build houses for the poor and homeless every Sunday? We would all meet at the work site, he would preach for ten minutes on Christ's moral teachings, take the sacrament, and then we would get to work.

Now what if every single stake decided to take a similar course of action every single Sunday for the next fifty years? Do you think we could solve some of our society's problems?
