I wonder, how many of us seriously ponder the value of holding the Aaronic and melchizedek preisthoods. when we consider how few people who have lived on the earth and have received the preisthood, and how Jesus christ has trusted those people to act in is name, we should feel pretty humble and grateful for the preisthood we hold..
The preisthood is the authority to act in the name of God. that authority is essentail to the fulfillment of his work on earth. the preisthood we hold is a delegated portion of the eternal authority of God. Now, as we are true and faithful, our ordination to the pristhood will be eternal. however.. the conferring of authority alone does not of itself bestow the power of the pristhood, the extent to which we can exercise the power of the pristhood depends upon personal worthiness, faith in the lord jesus christ, and obedience to his commandments.

Thomas S. Monson "When Supported by a secure foundation of gospel Knowledge, our capacity to worthily use the preisthood is greatly enhanced"

Very often the value of something is not recognized until it is taken away from us. You shouldnt have to lose your priesthood to appreciate it more fully.

The Perfect role model for use of the holy preisthood is our savior, Jesus Christ. he ministered with love, compassion, and charity. his life was a perfect example of humility and power. the greatest blessings from the use of the preisthood come from humble service to others without thought of self. by following his example as a faithful, obedeient preisthood holder, we can exercise the power of healing, of blessings, and of counseling, as the quiet promptings of the spirit are followed.

The purpose of the priesthood is to give, to serve, to lift, to inspire, and to build the kingdom of God. as an Aaronic priesthood
