Yet I do not feel afraid, alone, insignificant, or distant from God. For I have witnessed His priesthood power connecting with clean hands and pure hearts on a tiny island in a vast ocean. Brethren, that connection is available to all of us, no matter where, when, or under what circumstances we live, so long as our hands, hearts, and minds are clean and pure. There is no individual power in the priesthood outside of individual purity. We simply must work harder at purifying our lives by serving others in more Christlike ways.
Noble service requires hard work, deep sacrifice, and complete unselfishness.
The more the sacrifice, the greater the resultant purity. God, who is full of light, life, and love, wants us to hold and properly use His priesthood so we can transmit that light, life, and love to all about us. On the other hand, Satan, the prince of darkness, wants to hold back light, life, and love as much as he can. Since there is nothing Satan can do about the power of the priesthood, he concentrates his energy on trying to limit our individual power in the priesthood by attempting to dirty our hands, hearts, and minds through abuse, anger, neglect, pornography, selfishness, or any other evil he can entice us to think or do. Remember, the sand castles we build on the beaches of mortality, no matter how elaborate, will eventually be washed away by the tide.
