I think first off the Priesthood holder needs to fully understand and appreciate the blessing hes has recieved and the power for good he can use it for if done in accordance with Gods will.Second, we should be living our lives that is in accordance of the commandments and doing all we can to know the will of our Father in heaven and be prepared to act according to his will in a moments notice. Third, Make certain we always realize that the power of the Priesthood is indeed a blessing and never be used unrightiously or without reverence.
