Priesthood

The priesthood is an important part of the gospel for men and women. Some people have a problem with it being given only to men. I can see how they feel, but I'm going to use my husbands words to explain.
Men and women are clearly different. It can be said that generally women are closer to the spirit and have a more service oriented attitude than men. Men are good but get focused in and can miss stuff. Men have the priesthood to give service and as an opportunity to be closer to God. The priesthood can never be used selfishly. It can only bless others. A priesthood holder can never bless himself.
Although the priesthood is only given to men, it equally blesses men and women. It is a way to use God's power to serve others.
Eve was made for Adam as a helpmeet. Adam goes to the Lord and is guided. Eve is guided by what Adam was told by the Lord. So it makes sense that Adam would have the priesthood since he is the one directly guided by the Lord and Eve receives full benefits through Adam. There is an order and the order makes sense.
