Elder Nelson said this concerning the priesthood that impressed me lately:

"Available to each of you brethren and sisters are blessings obtained through the power of the holy Melchizedek Priesthood. These blessings can change the circumstances of your lives, in matters such as health, companionship of the Holy Ghost, personal relationships, and opportunities for the future. The power and authority of this priesthood holds the keys to all spiritual blessings of the Church. And most remarkably, the Lord has declared that He will sustain those blessings, according to His will."

I know the priesthood is a great power and blessings are given through righteous priesthood holders.
